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.

A website called GeneMatcher has helped researchers identify a new gene for intellectual disability, developmental delay and autism.

Two imaging techniques together reveal architectural features of the brains of preterm infants.

Molecules from alpacas may enable scientists to identify cell types in the brain while also revealing their interior structures.

A top autism gene called SCN2A plays a role at neuronal connections into adulthood, offering hope for treating mutations after infancy.

Autism and intelligence share genetic variants, researchers grow Neanderthal mini-brains and see overlap with autism, and maternal diabetes is an autism risk factor.
