Scientists have discovered more than 100 new proteins at junctions in the brain that dampen neuronal activity.

A mutation that prevents some amino acids, the building blocks of proteins, from entering the brain may lead to autism.

An experimental drug called arbaclofen improved autism features in about 13 percent of people who took it in a shuttered clinical trial.

Our infographic displays efforts to develop treatments for fragile X syndrome. So far, none of them have passed muster in clinical trials.

Lowering the levels of OTX2, a protein found in the fluid that bathes the brain, prevents many abnormal behaviors in mouse models of Rett syndrome.

A pair of existing drugs normalizes the appearance and activity of neurons derived from the skin of individuals with Rett syndrome.

A new study reveals how chemicals in the newborn brain forge connections between neurons.

Cells derived from the skin of boys and men with autism share a host of unusual characteristics.

Manipulating MeCP2, the gene mutated in Rett syndrome, has revealed two neuron types as crucial contributors to the condition.

A chemical commonly used in emergency rooms can anesthetize mice and rats for brain scans without distorting the images.
