A flexible electrode array can eavesdrop on neurons in people without damaging brain tissue.

The new director of the National Institute of Mental Health says work on brain circuits may yield treatments for autism.

A modified version of an existing imaging technique creates crisp images of neurons communicating in living mice.

A mutant virus that infiltrates neurons and delivers genes to the nucleus can illuminate brain connections.

Sensory abnormalities could be among the first signs of autism risk — and a target for early treatment.

People with autism who are acutely sensitive to smells have unusually weak connections between a brain region that processes social stimuli and one that integrates sensory information.

A new tool spots shared patterns of brain connectivity among people who have autism, schizophrenia or major depressive disorder.

Two mouse models of autism have distinct patterns of brain connectivity that emerge at different times.

Brain scans of sleeping children with autism reveal reduced synchrony between a brain region that processes emotions and structures involved in social communication.

A new method transforms lab-made stem cells into microglia, the brain’s immune cells.
