Differences in myelin, the insulation that surrounds neuronal projections, may shade measurements of cortical thickness on brain scans, a new study suggests.

A growing body of evidence shows that brain cells called oligodendrocytes may play a larger role in autism than previously thought.

A new approach for delivering gene therapy to the brain reduces nerve damage in primates and could help make gene therapies for conditions related to autism safer.

A new method automatically reconstructs the 3D branching shapes of neurons from images.

The long fibers of neurons in the brains of young children with autism are structured differently from those of their neurotypical peers — and from those of older children with the condition.

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

A new resource that traces individual neurons in the mouse brain may reveal how distant brain regions communicate.

Mutations in an autism gene called ANK2 may alter brain wiring by causing the growth of excess neuronal connections.

A novel cell culture device enables researchers to grow bundles of nerve fibers from stem cells, mimicking the tissue that connects distant parts of the brain.

Mice that lack a segment of chromosome 22 — a mutation associated with autism — have unusually sparse connections between brain regions.
