Cognition and behavior: Brain volume signals repetitive behavior

by  /  10 May 2011

Smaller-than-normal volume in several brain regions, including a region involved in relaying motor signals, could be a marker for repetitive behavior in 3-year-old children, according to a study published 7 April in Autism Research.

Brain expands too fast, shrinks too soon in autism

by  /  7 February 2011

The brains of people with autism show three distinct periods of abnormal development — overgrowth in infancy, prematurely arrested growth in childhood, and shrinking between adolescence and middle age — according to a study in Brain Research.

Brains of children with autism change as they grow up

by  /  17 November 2010

The brains of children with autism show differences in gene expression compared with those of healthy controls, especially in genes that control cell growth. Adults with autism also have aberrant gene expression, but in different pathways, researchers reported Sunday at the Society for Neuroscience annual meeting in San Diego.
