The overproduction of proteins in brain cells called microglia causes social impairments, cognitive deficits and repetitive behavior in male mice, a new study has found.

The mood-stabilizing drug lithium seems to ease repetitive behaviors seen in mice missing SHANK3, an autism gene.

Individuals with mutations in an autism gene called TRIO may have a range of conditions, including intellectual disability and anomalous head size.

A new wiring diagram of the fruit fly brain is the most complex ever created.

A new technique allows researchers to transplant human microglia into mouse brains and better study the association between these cells and autism.

Injecting the gene-editing tool CRISPR into the brains of mice may reverse the effects of an autism mutation at any age.

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.

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.

Two new maps show the entire nervous system of the adult roundworm Caenorhabditis elegans.
