A single seizure early in life leads to enduring behavioral problems, including diminished sociability, in mice.

Mouse models of two genetic conditions related to autism show abnormalities in their movement patterns.

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.

A molecule made by mitochondria, the energy factories of cells, might help doctors forecast the impact of mutations in a top autism gene.

Brain activity patterns in the first year of life may predict autism in infants at high risk for the condition.

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

Cardiac activity could reveal autism’s physiology and confirm a hunch many clinicians share: that people with autism experience great stress.

Autistic children who lose words reach key milestones earlier than autistic children without language regression.
