A trial of umbilical cord blood as a treatment for autism has passed a critical safety test, but many researchers remain skeptical of the approach.

A brain circuit that controls movement is altered in people with autism, a postmortem brain study suggests.

Children with autism who are highly anxious tend to move their heads during brain scans and so may be excluded from important studies.

Bundles of nerve fibers that bridge brain areas develop rapidly during the first six months of life. Fibers that connect language regions mature more slowly than those linking motor regions.

Infants who are later diagnosed with autism show inconsistent patterns of brain waves in response to the same sound.

A boost in the activity of microglia, the brain’s immune cells, during gestation may predispose boys to autism.

A new method for examining blobs of neurons known as ‘mini-brains’ reveals structures like those in the human brain.

Children with autism who have both severe repetitive behaviors and sensory sensitivities tend to have had unusually structured nerve tracts in infancy.
