Common brain malformation confers high risk for autism

by  /  29 May 2014

About one in every three adults who lack a brain structure called the corpus callosum meet the diagnostic criteria for autism, according to a study published 25 April in Brain. However, not all of these people develop symptoms in early childhood, as is typical in autism.

Molecular mechanisms: Mice link brain region to autism

by  /  21 May 2013

A strain of mice with autism-like behaviors is missing a corpus callosum, a bundle of nerve fibers that connects the two hemispheres of the brain. Two studies published this month investigate the link between these two features.

Lack of corpus callosum yields insights into autism

by  /  2 May 2013

A rare birth defect offers a unique perspective on the connectivity theory of autism. Up to one-third of those missing all or part of the corpus callosum, a thick tract of nerve fibers connecting the left and right brain hemispheres, meet the diagnostic criteria for autism, several recent studies suggest.
