Introducing the gene UBE3A into neurons that dampen brain activity prevents seizures in a mouse model of Angelman syndrome.

Drugs that block certain brain enzymes could help treat two conditions associated with autism.

Music therapy proves ineffective for autism, brain structures differ with 16p11.2 duplications and deletions, and mice missing NLGN3 may influence the sociability of their littermates.

Turning on a set of neurons that dampen brain activity improves social behavior in a mouse model of autism; turning off neurons that excite brain activity does the same thing.

A drug that alters the balance of two key chemical messengers in the brain may help treat autism, suggests a proof-of-principle study.

Negative experiences, such as being bullied or socially isolated, may lead to hallucinations.

A brain circuit that controls movement is altered in people with autism, a postmortem brain study suggests.

A drug used to treat excessive swelling seems to ease autism features in some children on the spectrum.

Removing the Rett syndrome gene, MeCP2, from distinct cells and brain regions reveals hidden features of the condition.

Researchers have traced an unusual maternal behavior in female mice modeling Rett syndrome to a neural circuit that processes sound. They have also found a drug that reverses this behavior.
