NeuroTribes: Heilpädagogische Station

Hans Asperger

Hans Asperger worked in the Children’s Clinic in the University of Vienna Hospital. This was no ordinary clinic, and author Steve Silberman argues that it was a century ahead of its time. It was created in 1911 by a doctor, Erwin Lazar, who, instead of seeing children with special educational needs as being "broken" or as having an "illness," saw them as needing different teaching methods more suited to their own learning styles.
Lazar’s progressive pedagogy was based on the 19th-century concept of Heilpädagogik, or "therapeutic education," and his special education unit was known as the Heilpädagogische Station. Hans Asperger worked there with Sister Viktorine using art, drama, music, literature and nature study. The antithesis of a custodial institution, it was a place where children and teenagers could discover their potential.


Asperger coined the term Autistische Psychopathen (autistic psychopathy) or Autismus for short to describe the children in his special education unit. In them he saw children with the minds of geniuses, eccentrics, obsessed with their special interests, some with amazing memories who could recall all the routes of the Viennese tramlines, others who could perform rapid arithmetical calculation, and others with profound learning difficulties. 

When he submitted his thesis describing these children in 1943, he argued that many of them had a natural aptitude for science, for example giving a portrait of a child who was obsessive with performing chemistry experiments at home. He saw them as potential innovators, seeing the world with a fresh perspective, and called them his "little professors." While he recognized how broad the autism spectrum was, he emphasised their special talents, not their "degenerate defects."

Professor Asperger gave the first ever public lecture on autism on October third, 1938, in a lecture hall in the University Hospital. He declared, "Not everything that steps out of the line, and is 'abnormal,' must necessarily be 'inferior.’"

In the News: Scientists Make a Finding in Understanding the Role ofGABA Pathways in Some Autism Symptoms




Researchers have connected autistic behavior to problems in GABA pathways, an important inhibitory neurotransmitter in the brain.

By Julia Lurie 

Last week brought some news in the autism research world: scientists have found a direct link between autistic behavior and a neurotransmitter, GABA, a kind of brain chemical that communicates information from one nerve cell to another. 

In a study published in the journal Current Biology, scientists at Harvard and MIT found that some symptoms of autism appear to stem from problems processing gamma-Aminobutyric acid, or GABA. 

An inhibitory neurotransmitter, GABA stops brain cells from acting in response to information they receive from the senses.

"Autism is often described as a disorder in which all the sensory input comes flooding in at once, so the idea that an inhibitory neurotransmitter was important fit with the clinical observations," said Caroline Robertson, the lead researcher, in a statement. While many of us can simply tune out everyday sights or sounds -- say, the sight of a grate on the sidewalk or the noise of a car driving by -- those with autism are inundated with a deluge of sensory information that can turn everyday environments into distressing experiences.

In addition, Robertson added, about 25 percent of autistic people also have epilepsy -- a result of "runaway excitation in the brain."

In the study, participants started with a visual test: Looking through binoculars, they would see two different images in both eyes -- say, a house on the left side and a car on the right side. Most people can focus on one image while diminishing focus on the other, and then switch, oscillating back and forth between the car and the house. In essence, inhibitory neurotransmitters enable the brain to process digestible pieces of information rather than try to take in everything at once.

But people with autism have a difficult time with this visual task -- the oscillation between images is slower, and the focus on one image is less directed. Within both groups, though, there's variation in how well people can perform the task. When the participants took part in a neuroimaging test that measured the amount of GABA, an unsurprising trend appeared for people without autism: The better people are at visual processing, the more GABA they have. For people with autism, though, there was no such trend: Those who were better at visual processing had no higher or lower levels of GABA than those who weren't, suggesting a problem with the way that GABA is used or processed.

"It's not that there's no GABA in the brain," said Robertson, "It's that there's some step along that pathway that's broken."

The finding is especially notable because GABA inhibits all kinds of sensory stimulation -- not just visual. In theory, a drug that targets bettering the GABA pathway could reduce sensory symptoms of autism.

Still, Robertson warns that this research isn't a "magic bullet" -- especially since scientists still know so little about autism and what causes it. "There are many other molecules in the brain, and many of them may be associated with autism in some form," she said. "We were looking at the GABA story, but we're not done screening the autistic brain for other possible pathways that may play a role."

In the Blogs: Stressed? This Dog May Help



By Michele Hollow 

Each morning, Cali, an 18-month-old Rhodesian Ridgeback, patiently waits for the K-12 students to pass through the doors of the Calais School in Whippany, N. J. As they walk by, Cali sniffs each one.

The students, about 85 in all, smile at the short-haired dog but know not to pet or distract her while she is working. Cali is a cortisol detection dog, trained to detect the stress hormone our adrenal glands secrete when we become anxious or stressed.

When we are agitated, cortisol levels in our bloodstream rise. It’s Cali’s job to let Casey Butler, her handler, know if a student’s cortisol levels are high. If they are, that student spends time talking with Ms. Butler and Cali to help defuse the stress. “The children feel safer with Cali around,” she explained. “They tend to open up more.”

Cali’s signals are so subtle that the students and other teachers waiting nearby rarely notice. But Ms. Butler, 25, pays close attention to see if Cali points with her nose and stares at a child.

Many of the students at Calais are on the autism spectrum; some have attention deficit disorder, oppositional defiant disorder and other challenges that can trigger anxiety and other difficult emotions.

Like most service dogs, Cali is extremely quiet and unassuming. “The students don’t like it when a dog jumps on them,” explained Ms. Butler, a health teacher who is a certified specialist in natural canine behavior rehabilitation and in animal adaptive therapy.

Cali was brought to the school last year from a local nonprofit called Merlin’s Kids that trains service dogs to work with special-needs children. “Some schools with a special-needs population have service dogs that visit and work with the students as a once-in-a-while activity,” said David Leitner, executive director of the Calais School. “We thought having a service dog on staff would benefit our students.

It was a decision that was presented to the teachers and staff at the school, and met without opposition. “A lot of us know people with service dogs, and we have seen how beneficial they are,” said Diane Manno, the principal at Calais. “And in just a short time, we have seen how Cali has helped our students.”

When Cali spots an anxious student, and Ms. Butler asks the student whether he or she is feeling stressed, the typical response is “I’m O.K.Ms. Butler counters by saying, “Cali told me otherwise.”

They listen to her because Cali is nonthreatening, and they like being around her,” Ms. Butler said.

A ninth grader agreed. “Cali can help us cope with our problems so that we don’t have to get through it by ourselves,” she said. “She is loving, intuitive and goofy.”

A few weeks ago, in Ms. Butler’s office, Cali started pacing, alternately moving toward the door and nudging Ms. Butler.She led me up one flight of stairs to the opposite end of the building, where we found a girl starting to have a meltdown,” she said.

Noticing Cali, the student asked if she could pet her. Ms. Butler told her not yet. “I first make sure Cali is safe,” she said. “Within a few minutes of seeing Cali, the student calmed down.” Only then does she reward students by letting them pet, brush and — sometimes — walk Cali.

It’s their uncanny sense of smell that allows dogs like Cali to detect rising cortisol levels in our sweat or breath, and identify a student having trouble even in a faraway classroom, said Nicholas Dodman, director of the Animal Behavior Clinic at Cummings School of Veterinary Medicine at Tufts University. “Humans have 12 million smell receptors in their nose. At the lowest estimate, dogs have 800 million. Scent hounds like beagles and bassets have up to four billion. A dog’s ability to smell odors is beyond our comprehension.”

We are proud of ourselves when we drive past Burger King and can smell that they are cooking burgers,” he said. “Dogs can smell a burger being cooked in the next town. That is why dogs are used to detect melanomas, diabetes and other types of disease. It’s all about the sense of smell.

Cali can also detect when a student is faking. “I’ve had students come into my office saying they don’t feel well,Ms. Butler said. “It’s not uncommon for a student to want to miss a class or a test. If Cali doesn’t signal when she sniffs them, I send them back to the classroom.”

At the end of the school day, the students board the buses back home, and Cali goes home with Ms. Butler. In a few weeks a second service dog will join the crew, a beagle named Cleo, an occupational and speech therapy dog. The students will work with Cleo to improve their fine motor skills by opening and closing the buttons and snaps on her harness, and will practice their oral and social skills by reading to her.

The students are eagerly standing by.

In the News: ADHD, Autism, Schizophrenia, Other Psychiatric Disorders Genetically Linked In Huge New Study

In response to ischaemia (a reduction in blood flow), the neurotransmitter glutamate is released from neurons and other brain cells (astrocytes; not shown). This induces Ca2+ entry (green arrows) into responsive neurons through NMDA-type glutamate receptors and Ca2+-permeable AMPA-type glutamate receptors. Ca2+ also enters through voltage-gated Ca2+ channels and several other types of Ca2+-permeable membrane channel, and is released from intracellular stores. The NCX proteins represent a primary cellular defence against Ca2+ overload, pumping Na+ ions in and Ca2+ ions out. But Bano et al.1 show that in ischaemic conditions NCX is destroyed by the Ca2+-activated protease calpain.

Washington — The largest genetic study of mental illnesses to date finds five major disorders may not look much alike but they share some gene-based risks. The surprising discovery comes in the quest to unravel what causes psychiatric disorders and how to better diagnose and treat them.

The disorders – autism, attention deficit-hyperactivity disorder or ADHD, bipolar disorder, major depressive disorder and schizophrenia – are considered distinct problems. But findings published online Wednesday suggest they're related in some way.

"These disorders that we thought of as quite different may not have such sharp boundaries," said Dr. Jordan Smoller of Massachusetts General Hospital, one of the lead researchers for the international study appearing in The Lancet.

That has implications for learning how to diagnose mental illnesses with the same precision that physical illnesses are diagnosed, said Dr. Bruce Cuthbert of the National Institute on Mental Health, which funded the research.

Consider: Just because someone has chest pain doesn't mean it's a heart attack; doctors have a variety of tests to find out. But there's no blood test for schizophrenia or other mental illnesses. Instead, doctors rely on symptoms agreed upon by experts. Learning the genetic underpinnings of mental illnesses is part of one day knowing if someone's symptoms really are schizophrenia and not something a bit different.

"If we really want to diagnose and treat people effectively, we have to get to these more fine-grained understandings of what's actually going wrong biologically," Cuthbert explained.

Added Mass General's Smoller: "We are still in the early stages of understanding what are the causes of mental illnesses, so these are clues."

The Psychiatric Genomics Consortium, a collaboration of researchers in 19 countries, analyzed the genomes of more than 61,000 people, some with one of the five disorders and some without. They found four regions of the genetic code where variation was linked to all five disorders.

Of particular interest are disruptions in two specific genes that regulate the flow of calcium in brain cells, key to how neurons signal each other. That suggests that this change in a basic brain function could be one early pathway that leaves someone vulnerable to developing these disorders, depending on what else goes wrong.

For patients and their families, the research offers no immediate benefit. These disorders are thought to be caused by a complex mix of numerous genes and other risk factors that range from exposures in the womb to the experiences of daily life.

"There may be many paths to each of these illnesses," Smoller cautioned.

But the study offers a lead in the hunt for psychiatric treatments, said NIMH's Cuthbert. Drugs that affect calcium channels in other parts of the body are used for such conditions as high blood pressure, and scientists could explore whether they'd be useful for psychiatric disorders as well.

The findings make sense, as there is some overlap in the symptoms of the different disorders, he said. People with schizophrenia can have some of the same social withdrawal that's so characteristic of autism, for example. Nor is it uncommon for people to be affected by more than one psychiatric disorder.

Self-Stimulatory Behaviors (A.K.A Stimming)


Mmmm --- beta-endorphins.




What is Stimming?

Stereotypy or self-stimulatory behavior refers to repetitive body movements or repetitive movement of objects. These movements are used solely to stimulate one’s own senses. This behavior is common in many individuals with developmental disabilities; it appears to be most common in children and adults with autism. It is important to note that not all self-injurious behaviors are considered to be self- stimulatory. Self-injurious behavior can also be communicative (see below).

What are some symptoms of stimming?
Stimming symptoms include: gazing at a wall or fixating on an object; repetitive body movements such as rocking back and forth; repetitive movement of objects, such as turning on and off light switches.

Here are some stereotypical stimming behaviors.

Visual: Staring at lights or ceiling fans; repetitive blinking; moving fingers in front of the eyes; hand-flapping, gazing at nothing in particular; tracking eyes; peering out of the corners of eyes; lining up objects; turning on and off light switches.

Auditory: Vocalizing in the form of humming, grunting, or high-pitched shrieking; tapping ears or objects; covering and uncovering ears; snapping fingers; making vocal sounds; repeating vocal sequences; repeating portions of videos, books or songs at inappropriate times.

Tactile: Scratching or rubbing the skin with one’s hands or with another object; opening and closing fists; tapping surfaces with fingers.

Vestibular: Rocking front to back; rocking side-to-side; spinning; jumping; pacing.

Taste: Placing body parts or objects in one’s mouth; licking objects.

Smell: Sniffing or smelling people or objects.

Why might my child be engaged in stimming?

Children with Autism Spectrum Disorder engage in stimming for a variety of reasons. One explanation is that it releases opiate-like substances in the brain called beta-endorphins, which can produce either a euphoric or anesthetic effect. Others believe that stimming could be due to the mechanism that provides: (a) an extra dose of internal stimulation for children with ASD who feel under-stimulated or (b) a feeling of tranquility for children who feel overstimulated.

Children who are hypersensitive, or overly sensitive to stimuli, may engage in stimming because they want to reduce their current level of stimulation, whether they perceive their environments as too loud, bright or crowded.

Children who are hyposensitive, or under-responsive to stimuli, may demonstrate the opposite effects: stimming may actually increase arousal. They may engage in self-stimulatory behaviors that provide them with an extra dose of sensory excitement, such as flapping or spinning, licking toys, sucking on household objects, or standing at sinks and running their hands under cold water.

In extreme instances, stimming may take on the form of self-injurious behavior. Examples include head banging, eye poking, and handing biting. Not all self-injurious behaviors are considered self-stimulating. Self-injurious behavior can also be communicative; children may hit their heads because they are frustrated and unable to tell their parents or caretakers what they want.

How might I help treat my child’s stimming?

Evidence suggests that the combination of positive reinforcement for functional responses with deceleration techniques (i.e extinction or over-correction) may provide an effective means of reducing self-stimulatory behavior and will help teach appropriate replacement behaviors.

Clay Marzo: In His Element

Clay Marzo is a prodigy in the water, but on land he struggles to keep up

by Alyssa Roenigk. ESPN the Magazine, September 7, 2009
It's been less than 48 hours since Clay Marzo was in the water, but that feels like a lifetime. Two days ago, while surfing near his home on the northwest shore of Maui, Marzo wiped out and was dragged across the razor-sharp reef. The cuts on his stomach are deep, the pain intense. Today, a warm October Wednesday, he can't even lie on his board.


Injury days are rare for Marzo, which is fortunate because time out of the water is debilitating. Not because of the physical pain -- that he can handle. But because on land Marzo struggles to communicate, to fit in, to breathe. All his life, he has struggled in social situations, and two years ago he finally found out why. Marzo, 20, suffers from Asperger's syndrome, a high-functioning form of autism. "I always knew something was different about me," says Marzo, his aqua eyes avoiding contact, the movements of his long, lean body visibly less fluid on land.


Different like this: The wiring in Marzo's brain makes it difficult for him to perform certain normal functions, such as reading facial expressions or recognizing social cues. As a result, simple acts of meeting people, attending parties and doing media interviews -- all requirements for a professional surfer -- are painful in a way that the cuts on his abdomen are not. In crowds, Marzo feels overwhelmed and exhausted. At group dinners, the stress of trying to follow multiple conversations causes headaches and nausea. Because he has difficulty coping with others, he's had a hard time making friends. People have called him strange and weird and, often, much worse.


But there's a flip side to his AS, a "benefit" of the condition that many with Asperger's have used to their advantage. The condition allows Marzo to laser-focus on a single activity, turning his greatest challenge into his greatest asset. Most people get bored after an hour or two of the same activity. Not Marzo. When he surfs, he goes into a zone, focused and lost at the same time. He calls an eight-hour surf session, with no breaks for food or water, "the perfect day." He'll then spend eight more hours watching video of his session, replaying each wave, over and over.




Sean DaveyMarzo has learned that the very thing holding back is also what makes him great.


Long before his Asperger's was diagnosed, Marzo and his parents recognized the paradox of his personality. In school he had trouble sitting still, comprehending directions or understanding what he read. "I could connect, could focus, if I really liked something," Marzo says. "But if I didn't, I couldn't focus at all." He'd flap his arms when he was anxious and rub his hands together when he was excited -- called stimming by autism specialists. He'd spend hours alone, obsessing over seashells or baseball cards. He was hypersensitive to sound and touch and would leave the table midway through family dinners or disappear to his room during the excitement of Christmas morning. When his routine was altered, especially if it kept him out of the ocean, he turned moody.


"Now I know those were all typical behaviors of someone with Asperger's," says Marzo's mom, Jill, a massage therapist. But for years, all the Marzos knew was that Clay best understood the world through the prism of surfing. They knew that's where he thrived, so Jill and husband Gino, who works in construction, nurtured his talent. "Clay is alive in the water," Jill says. "When he's not in the ocean, he is uncomfortable in his own skin."


In water, Marzo was a prodigy. He won a state swimming title at 10, and at 14 he caught the eye of execs at Quiksilver with his board skills. Marzo's older half-brother, Cheyne Magnusson, had a Quik sponsorship and recommended his kid brother, saying, "He's the real talent. He's the real deal." Marzo sealed the deal by sending a self-edited video of himself surfing local Maui spots to Strider Wasilewski, the company's team manager.


Wasilewski was instantly impressed. While most teen surfers are mastering bottom turns and cutbacks, Marzo was doing tailslides, reverses and controlled boardslides on the lip. "I'd never seen a kid at that age do those things," Wasilewski says. "Some of what he did was mind-blowing at any age. It was like someone had sent me the instructions to create the first nuclear bomb. I knew I'd received a package that would change the face of surfing."


A few months later, Wasilewski invited Marzo on a trip to the Mentawais to film Young Guns II, a surf video featuring hot up-and-comers Dane Reynolds, Fred Patacchia and Ry Craike, as well as nine-time world champ Kelly Slater. Marzo left quite an impression. "Clay is a freak on a surfboard," Slater says. "He does things people don't even think of. He just sees the wave his own way." In the water, he was relaxed and talkative. But on the boat, he'd walk away from people in midconversation, disappear at important moments and take others' cell phones and towels without asking, then lose them without apology. On the junior contest circuit, the story was the same; Marzo amazed with his flashy skills and offended with odd behavior. He has a catlike ability to stay up on his board, bending and contorting his body into seemingly impossible positions, and he was not shy about taking huge risks, often with disastrous results. Even when he just needed to ride out a wave to advance through a heat, Marzo would throw big tail-first snaps, land backward, or fly off the lip and spin a 360.



Sean Davey Though he struggles on land, Marzo often surfs nonstop for as long as eight hours.

"It was hard to watch," Gino says. "Other kids played it safe, but Clay went big on every wave." That in-the-moment attitude is another characteristic of people with Asperger's, who are so "in the now" that they seldom consider the consequences of their actions. When Marzo rode well, he was tough to beat. At 15, he won the men's open division at the 2005 NSSA championships, where he scored two 10s in the final. But his risk-taking almost upended his career.

As word of Marzo's free-surfing and tube-riding skills spread, requests for appearances, signings and group trips increased. But the more he was pushed into public situations, the more erratic his behavior became. He blew off many events and acted standoffish when he did show up. Marzo's quirks, previously overlooked because of his ability, began to make him a liability, especially when contest results slipped. At the 2005 world juniors, Marzo needed a 6. He could have won the contest by simply standing on a wave and doing a couple of turns. "Instead, he went for a crazy air and fell," says Quiksilver marketing director Jamie Tierney. "He lost."

To the outside world, Marzo looked like he didn't care -- about winning, about participating, about playing the game. "He was becoming a problem, and people wanted to let him go," Wasilewski says. "But I knew this kid wasn't stoned or stupid. He wasn't a spoiled teenager who didn't want to be there. I could see him freaking out inside. He was in pain." Wasilewski suspected Marzo might have some type of neurological disorder and found a self-test for Asperger's on the Internet. "It defined Clay to a T," he says. "I said, 'This is it. This is Clay's challenge. This is his gift.'"


Wasilewski and Tierney called Jill to ask if they could take Marzo for a formal evaluation and film the process. At first, she said no. But Wasilewski persisted, telling Jill: "Clay has a gift. He can be a surfing prophet. Or he can live in Honolua Bay surfing secret spots by himself." The Marzos finally said okay. "You want to protect your son, keep him safe," says Gino. "But we trusted that this was bigger than surfing. They wanted to affect peoples' lives."

In December 2007, during three days of exams with specialists Michael Linden and Chitra Bhakta in Southern California, Marzo underwent written tests, interviews, a family-history review and a QEEG test, which maps brain activity, showing where Marzo's brain was overaroused and underactive. Linden's conclusion: "Clay has Asperger's and symptoms of ADD and OCD."


Far from being upset, Marzo and his parents were relieved by the diagnosis. For Marzo, identifying his condition was a release that allowed him to embrace the two sides of his life. He now understands why social situations remain a daily challenge yet he can surf like few others in the world. The diagnosis has also brought a measure of respect from the surf world, an understanding of his genius. For example, because Marzo has spent so much time in the water, experiencing and studying the motion of waves, his peers believe he understands aspects of surfing that they may never comprehend -- that Marzo is to surfing what Einstein was to science and Mozart was to music. (Some experts believe both men, known for social awkwardness and single-minded brilliance, had Asperger's.) "It's a gift," Marzo says. "With surfing, with the way I see the world, with everything. It's definitely my gift."



Doomas/A-FrameYou can see Marzo surf in the documentary Clay Marzo: Just Add Water.


In the two years since the diagnosis, Marzo has been learning to bridge the gap between the calm of the water and his chaos on land. He attends biweekly therapy sessions, which teach him how to both recognize and give social cues and help him maintain calm in group situations. He has also scaled back his competition schedule. Instead of trying to qualify for the world championship tour, he focuses on video trips and photo shoots. "In surf culture, we've always had misfits and oddball characters," Tierney says. "So why would we ask a kid who's not a contest robot to become one? Clay is so much more interesting than that."


When he does compete, Marzo chooses events carefully. He went to the Quiksilver Pro in late August, in Puerto Escondido, Mexico, because the water is warm and feels like home, the surf big and barreling, and the break familiar -- he was on the team that won X Games gold on those waves in 2007. The competition wasn't nearly as much of a draw as the chance to surf barrels in a spot worth leaving home for. Yes, he notched one of just two perfect 10s at the event. And, yes, he won his first pro contest with a confident, calculated, patient display of surfing. But his performance is almost beside the point. For Marzo, the trip to Puerto was simply about feeling whole, about riding waves, about surfing. It's always been about the surfing.

Marlene Behrmann: Connecting Autistic Behavior to Brain Function



Autism is a disorder that is well known for its complex changes in behavior -- including repeating actions over and over and having difficulty with social interactions and language.

Connecting these behavioral patterns to an underlying neural deficiency is imperative for understanding what gives rise to autism, to developing better measures for diagnosing those along the Autism Spectrum Disorder and designing more effective treatments.

However, even given our significant advances in understanding how the brain works, there hasn't been evidence to tie autistic behavioral patterns together with corresponding neural functions. Until now.

A team of researchers -- including myself and colleagues from Carnegie Mellon University, the University of Pittsburgh, New York University and the Weizmann Institute of Science -- were interested in trying to understand on a basic neural level what happens inside the brain that might give rise to the altered behaviors in autism. Instead of focusing on the more complex behaviors, we set out to uncover and measure fundamental neural responses -- the patterns of brain activation in individuals with autism compared to those without.

Using an fMRI at Carnegie Mellon's Scientific Imaging and Brain Research Center, we scanned the brains of 14 adults with autism and 14 without while these individuals responded separately to visual, auditory and touch stimuli. We looked at the way the most elemental part of the brain's cortex responded to these simple stimuli.

In typical individuals, every time they saw the same visual stimulus, they had an almost identical response in the primary visual system. The stimulus drove normal visual systems in the same way time and time again. So, the question was whether we would see the same kind of consistent responses in the visual, auditory and somatosensory, or touch, cortices and within autism. It was our belief that any alteration in brain response we saw would be a very powerful indication of a major characteristic of autism.

It turns out that in all three of the primary cortices -- visual, auditory and somatosensory -- we did not see the typical response trial after trial in the individuals with autism. Instead, we saw considerable variability -- sometimes a strong response, sometimes a weak response. The fact that we did not see precise responses in autism was a really important result. It suggests that there is something fundamental that is altered in the cortical responses in autism. This variability in the brain response might also possibly explain why individuals with autism find visual stimulation, touch and sound to be so strong and overwhelming.

We know from genetic research that many of the neurobiological changes that occur in autism have to do with changes at the level of the synapse, the way that information is transmitted from one neuron to another. What these results -- that autistic adults have unreliable neural responses -- does is begin to allow us to build a bridge between the kind of genetic changes that may have given rise to autism in the first place. It cracks open a new avenue of research which has a good potential to be highly informative in understanding the connection between the neurophysiology and the behavioral patterns in autism.

While this particular study involved high functioning autistic adults and fMRI, we are now running follow-up experiments using EEG. This method which will give us even more detailed information about the neural responses and will allow us to test individuals across the autism spectrum and across different age groups so that we can gain further understanding of this unreliable neural response profile. And, because unreliable neural activity is a general property that could have a profound impact on how many brain systems function, it could underlie not only autism but a range of cognitive and social abnormalities including epilepsy and schizophrenia.

We are at the tip of a huge iceberg here; further research to fill in the details of exactly how this unreliability happens is essential for accurately diagnosing and treating autism and other disorders. At places like Carnegie Mellon University, which established a Brain, Mind and Learning initiative to build from its excellence in psychology, computer science and computation to continue to solve real world problems, these types of research projects are a priority. Our ongoing collaborations with Center for Autism Research at the University of Pittsburgh, and with ABIDE, which shares autism imaging data from top research facilities around the world, are crucial for working together to make sure we have all of the scientific resources possible to conduct high quality research.

My Obsessive Reading



I have an "indexing gene." I love checklists and reference data. I used to catalogue the creative credits for my favorite comic books, in pencil, on 3" x 5" index cards, during the Anchorage Fur Rendezvous dogsled races televised in the mid-seventies. I thought it was fun. Like most collectors, I would also make ultra-detailed "want lists" of missing, desired issues, and reading lists of favorite authors.

For a time in the nineties, I joined legendary comic fan Jerry Bails' indexing apa (amateur press association), apa-i. I 've contributed to the online Grand Comic Book Database., Askart, and other databases -- the ultimate versions of my old catalog card system.

These days, when I finish a nonfiction book, I write down the title and author(s) in a notebook. Sometimes I forget, but usually I record the books soon after reading. In true OCD fashion, I have to actually finish a book in order to record it. Partially finished books don't count. Believe it or not, just seeing the title/author information again helps me recall much of what I've read.

I originally read popular science and math books for the nonfiction genre, but after the 2008 financial crisis meltdown, I realized I knew nothing of business, and went on a business, economics, and investing book jag. Then in 2010, I shifted gears again to the current trend of mainly psychology and neuroscience reads. The "Behavioral Economics" business books made a nice bridge to these psychology books. I think my "psychology phase" is winding down now. What's next? Probably learning theory.

For "extra credit," I have typed out my list of my obsessesive fact-based reading conquests. You might enjoy reading a few of them yourself, so I have roughly categorized them. Frankly, after typing out this list, I'm a bit blown away at how much material I've consumed so far, and this doesn't even count all the comics, art books, magazines, and crime novels. I'm sure I've also missed a few books that I forgot to record. Here's the list, alphabetized by author.
