Cognition and behavior: Symmetry skewed in autism brains

by  /  30 January 2013

Teenagers with autism have an atypical balance between the right and left sides of the corpus callosum, which connects the two hemispheres of the brain, according to a study published 23 November in the Journal of Autism and Developmental Disorders.

Cognition and behavior: Corpus callosum disrupted in autism

by  /  27 November 2012

Nearly half of children with malformation of the corpus callosum, which links the two hemispheres of the brain, have symptoms of autism, according to a study published 5 October in the Journal of Autism and Developmental Disorders.

Mice with autism-linked deletion show unexpected deficits

by  /  15 October 2012

Mice lacking one copy of the autism-linked 16p11.2 chromosomal region are thin, deaf and show repetitive behaviors. They also have altered proportions of neurons in their brains, particularly those that express the chemical messenger dopamine. The unpublished results were presented Sunday at the 2012 Society for Neuroscience annual meeting in New Orleans.

Autism risk gene found to alter brain wiring

by  /  13 September 2012

MET, a leading candidate gene for autism risk, influences the strength of connections between brain regions involved in social behaviors, and this effect is especially prominent in people with the disorder. The findings are from a large study using several imaging techniques, published 6 September in Neuron.

Cognition and behavior: Corpus callosum smaller in autism

by  /  4 April 2012

Children with autism have a smaller corpus callosum, a bundle of nerve fibers that connects the two hemispheres of the brain, compared with controls, and this difference persists over two years of development, according to a study published 18 February in the Journal of Autism and Developmental Disorders.

Cognition and behavior: Asperger brains similar across sexes

by  /  8 February 2012

The brains of men and women with Asperger syndrome are more similar than are those of male and female controls, according to a study published in the January issue of the American Journal of Neuroradiology. The results lend support to the ‘extreme male brain’ theory of autism, the researchers say.
