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.

Four new imaging techniques published over the past few months enable researchers to easily visualize cells and other features in tissue slices and living brains.

Spheres of brain cells derived from people and implanted into mouse brains recruit blood vessels and integrate with mouse neurons.

A new map reveals the routes of individual neurons in visual regions of the mouse brain.

The same techniques that generate images of smoke, clouds and fantastic beasts in movies can render neurons and brain structures in fine-grained detail.
