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

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

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.

A new system enables researchers to automatically track the social behavior of up to four mice for days at a time.

The timing of treatment is crucial for conditions related to autism — and more so for some conditions than for others.

Researchers have engineered two generations of monkeys with mutations in SHANK3, a top autism gene. The first generation shows traits reminiscent of the condition.

Autistic children may be more likely than their unaffected siblings to carry mutations in genes linked to sleep.

An experimental compound that blocks two enzymes involved in gene expression improves social behavior in young mice.

A brain region that orchestrates responses to social cues and aids decision-making may be off tempo in autism.
