A variant of the autism risk gene CNTNAP2 may alter the brain to emphasize connections between nearby regions and diminish those between more distant ones, according to a study published 3 November in Science Translational Medicine.

The parts of the brain that help us pay attention to some things and not others have specialized regions for different senses, such as sight and sound, according to a paper published online in November in the Proceedings of the National Academy of Sciences.
Areas of the brain that are active when people are daydreaming or sleeping, and quiet when they are engaged in a task, are imperfectly synchronized in people with autism and attention deficit hyperactivity disorder, researchers say.
Children with autism have an imbalance of excitation and inhibition in the brain, according to the first study to measure synchrony between brain networks using magnetoencephalography (MEG). The findings were presented Wednesday at the Society for Neuroscience annual meeting in San Diego.
Important language areas in the brain don’t show the expected patterns of connectivity when people with autism listen to speech, suggests a poster presented Monday at the Society for Neuroscience annual meeting in San Diego.
Brain imaging experiments often require the participant to perform tasks while lying inside a brain scanner for up to an hour — not a pleasant experience for anyone, let alone a child with autism. Saturday afternoon at the Society for Neuroscience annual meeting in San Diego, Steve Petersen described ‘resting state’ imaging, in which participants lie in the scanner for just five to ten minutes.
A new brain imaging technique may provide a powerful tool for understanding social interaction, and how it is disrupted in conditions such as autism, according to a poster presented Sunday at the Society for Neuroscience annual meeting in San Diego.
Counting neurons in the brains of people with autism who died young might strike some people as grisly or tedious. But Eric Courchesne sees it is the key to understanding why people with autism experience rapid overgrowth of certain brain regions early in life.
Siblings of children with autism who show no signs of the disorder may be compensating with increased activity in two brain regions that detect social cues, according to results presented yesterday at the Society for Neuroscience annual meeting in San Diego.
