A new algorithm accurately separates highly similar people into subgroups based on their brain activity — and could do the same for autistic people.

Loss of certain neurons on one side of the brain may explain why some autistic people are hypersensitive to touch.

The severity of autism tracks closely with that of attention deficit hyperactivity disorder.

Mice missing a copy of CHD8, a top autism gene, show a signaling imbalance in their brains — a finding in line with a popular hypothesis about autism’s origins.

New findings hint at why drugs that work in mouse models of fragile X syndrome have not been effective in people.

A new study supports the view that songbirds offer a good model to study speech learning in autistic children.

A novel implant that delivers complex combinations of drugs and light to mouse brains may uncover the pathways that underlie repetitive behaviors in autistic people.

Deleting the mutation from an autism gene may reverse some autism traits in mice, according to a new study. But the results may be a fluke.
