Studies of brain structure boost ‘connectivity theory’ of autism

by  /  21 July 2009

The brains of people with autism have structural abnormalities that disrupt normal connections between brain regions and impede the flow of information across the brain. That’s the conclusion of a 20-year-old theory supported by several new studies.

Brain images uncover candidate genes for schizophrenia, autism

by  /  12 May 2009

Applying an emerging technique that combines genetic data and brain scans, researchers have identified two new genes involved in schizophrenia. The method, called ‘imaging genetics’, holds promise for linking genes to brain function in complex psychiatric disorders, including autism.

Amygdala in autistic brains may not adapt to social stimuli

by  /  22 April 2009

The characteristic inability of a person with autism to respond to emotions may stem from sustained arousal in the amygdala, the brain region needed to interpret emotions from facial expressions.
