The Brain

Injecting cells called interneurons into the brains of a mouse model of autism restores typical social behavior. But the reason for this effect is a puzzle.

The social brain has a sweet spot that activates when people look each other in the eyes but not when they look at eyes in a video.

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.
