High levels of serotonin in the womb may up the risk of autism in the child, according to a study published in December in the American Journal of Medical Genetics.

Using tricks of genetic engineering, researchers in Taiwan have created the first comprehensive map of the myriad neuronal connections in the fruit fly brain. The findings appeared 11 January in Current Biology.

Depression in mothers of children with autism may not be a consequence of their child’s condition, but of their own genetic profile, says a provocative new study.

A controversial new approach that quiets the activity of certain neurons in the brain alleviates breathing difficulties in a mouse model of Rett syndrome, according to a study published 4 October in the Proceedings of the National Academy of Sciences.

People with autism may belong to one of four distinct categories based on their medical history, according to a study published in the October Autism Research.

Parents and siblings of people with autism have abnormal eye movements and score higher on tests evaluating traits associated with the disorder.

With robust training in developmental psychology and a techie’s fervor for new tools, Kevin Pelphrey is systematically investigating how the brain changes during development — starting in infants as young as 6 weeks old.

Mice engineered to carry a well-known risk factor for schizophrenia show disruptions in the connections between two brain regions that coordinate memory and learning. And these disruptions directly cause problems with working memory — the ability to actively hold information and to recall that information to make a decision, according to a study published in Nature.

Attention deficit hyperactivity disorder (ADHD) and autism may have more in common than childhood onset and a few similar symptoms. New research suggests the conditions share genetic roots.
