Autism Teachers

The upshot of these differences is that the columns in an autistic brain seem to be more connected than normal with their close neighbours, and less connected with their distant ones. Though it is an interpretative stretch, that pattern of connection might reduce a person’s ability to generalise (since disparate data are less easily integrated) and increase his ability to concentrate (by drawing together similar inputs).

Dr Snyder argues that savant skills are latent in everyone, but that access to them is inhibited in non-savants by other neurological processes. He is able to remove this inhibition using a technique called repetitive transcranial magnetic stimulation.

all the success stories related inside the pages of EPSS are accompanied by fortuitous exposure to various forms of structured material, clearly marking out the most promising path for autistic development and growth.

And of course these discussions fly in the face of the current clamor for early intervention in autism, where it would seem the goal is always to yank the autistic child away as early as possible from his or her preferred method of engaging the world, and substitute instead an intense bombardment of socially based indoctrination, hoping to turn the child around while there is still time for the “malleable” brain to be re-molded.

In my opinion, it is no mere coincidence that the very same elements that stand at the core of the Mottron team's affirmative description of autistic perception and cognition are also the very same elements that stand at the core of humanity’s sudden departure off the savannah and leap into the modern world.

Admittedly, a thorough discussion of such a topic would be much too large for inclusion in an academic research paper such as EPSS, but the fact that the Mottron team does not mention, or even hint at, the connection between the features of autistic perception and the features of human cognitive history leave it unclear whether the team has ever considered such a connection.

At this point in time, the Mottron team seems to be the only autism research team heading in a positive and enlightening direction—a direction that is constructive for autistic individuals everywhere—and I look forward to all their future contributions.

In 2006 your lab published a paper in Nature Neuroscience linking a mirror neuron dysfunction to autism. How might reduced mirror neuron activity explain the symptoms of autism?

Reduced mirror neuron activity obviously weakens the ability of these patients to experience immediately and effortlessly what other people are experiencing, thus making social interactions particularly difficult for these patients. Patients with autism have also often motor problems and language problems. It turns out that a deficit in mirror neurons can in principle explain also these other major symptoms. The motor deficits in autism can be easily explained because mirror neurons are just special types of premotor neurons, brain cells essential for planning and selecting actions. It has been also hypothesized that mirror neurons may be important in language evolution and language acquisition.

Thus, a deficit in mirror neurons can in principle account for three major symptoms of autism, the social, motor and language problems.

There is convincing behavioral evidence linking media violence with imitative violence. Mirror neurons provide a plausible neurobiological mechanism that explains why being exposed to media violence leads to imitative violence.

I think there are two key points to keep in mind. The first one is the one we started with: mirror neurons are brain cells specialized for actions. They are obviously critical cells for social interactions but they can’t explain non-social cognition. The second point to keep in mind is that every brain cell and every neural system does not operate in a vacuum. Everything in the brain is interconnected, so that the activity of each cell reflects the dynamic interactions with other brain cells and other neural systems.

Nonetheless, this incidence is about 100 times greater than the rate at which autism affects unrelated people in the population.

One study showed that the likelihood that the identical twin of an autistic child also would be autistic was 82 percent, whereas the equivalent rate for fraternal twins was only 10 percent.

With sophisticated statistical techniques and numerous twin studies, behavioral geneticists now believe that as much as 90 percent of the behavioral phenotype of autism is related to inherited genes.
