Some genes associated with autism may influence the thickness of the cerebral cortex, the brain’s outer layer.

Microscopic silicon wires could enable scientists to excite neurons with light without first inserting genes into them.

The amygdala, a brain region that governs emotions, may be enlarged and overly connected in children with autism, but it shrinks as the children grow up.

Microglia come into frequent contact with synapses, the connections between neurons, but they appear to nibble on them rather than engulf and digest them.

A new technology that converts near-infrared light to visible light can manipulate neurons nestled deep in the brain.

Deleting one copy of a gene called MVP impairs the brain's ability to adapt to changes in the environment.

Children with autism may have many of the cognitive difficulties seen in children with attention deficit hyperactivity disorder.

Many researchers question the value of three early mouse models of autism, but the models have their staunch supporters.
