A variant in a gene that regulates immune responses is more common in children with autism than in those without this disorder.

Overcoming profound technical challenges, researchers may be well on their way to making a troop of monkey models for studying autism and related conditions

Scientists have discovered a new way that microglia, the immune cells of the brain, can sculpt brain circuits.

Roughly one-sixth of the monkeys on an island off the coast of Puerto Rico may carry a variant in SHANK3, a top autism gene candidate.

Disrupting cell-to-cell contact among developing neurons, even briefly, may alter their fates for good.

By outfitting a child and a clinician with wireless motion sensors, researchers are quantifying the nuances of their social interaction in ways that may aid autism diagnosis.

Boosting levels of the fragile X protein FMRP in astrocytes reverses features of fragile X syndrome in mice.

Adults with autism struggle to reconcile conflicting visual information, hinting at a signaling imbalance in the brain.

Infants born prematurely show alterations in the structure and function of their brain circuits — findings that may help explain their increased risk for autism.

The same autism-linked mutation can lead to dramatically different behaviors in rats and mice.
