Autism may be caused by a dysfunctional corpus callosum, resulting in poor communication between brain hemispheres, a new study suggests. A defect in communication between the two halves of the brain may be responsible for some cases of autism, according to a study by researchers at the Stanford University School of Medicine
. They came to their conclusions by analyzing what's called the human interactome — a vast network of interacting proteins - and by sequencing genomes and analyzing gene expression patterns in individuals with autism. The study offers a possible explanation as to why the communication center of the brain, called the corpus callosum, is often abnormally small in people with the condition.
