The new technique can record hundreds of thousands of neurons firing nearly simultaneously across big swaths of brain tissue in living mice.

Mice missing the autism-linked gene SHANK3 use more neurons to engage in social behavior than control mice do, reflecting a more disorganized, less efficient brain signaling network.

A new miniature iteration of a popular probe enables researchers to record activity at thousands of sites across the mouse brain and track the activity of individual neurons over months — providing long-term recording at an unprecedented scale.

Merging 3D clusters of neurons that mimic different brain regions models the atypical electrical activity seen in an autism-related condition.

Connections between the cerebellum and brain networks do not seem to contribute substantially to the emergence of autism traits.

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

Babies with telltale patterns of electrical activity in the brain have pronounced autism traits as toddlers.

Autistic girls’ brains respond more strongly to social stimuli than do autistic boys’.

Areas of the brain involved in processing vision are more weakly connected to those that process sensory information in autistic children than in controls.
