A new wireless device switches oxytocin-producing neurons on and off in mice as they interact, showing the hormone’s effects depend on social context.

A new analysis links individual mutations in a gene called PTEN to a person’s odds of having autism, cancer or other conditions.

A trove of DNA sequences from 141,456 people — and counting — offers an unparalleled look at genetic variation.

A new high-resolution atlas provides the most detailed views of mouse brain structure to date.

A new method for electroencephalography source localization can noninvasively identify brain networks involved in generating seizures in people with epilepsy.

A new flexible electrode array can detect the activity of neurons in a rat’s brain at high resolution for more than a year.

A new, minimally invasive technique allows researchers to activate neurons in the brains of mice and monkeys by using a light source located outside of the head.

Brain imaging data reveal sex differences in regions linked to social contact.

Standardized tests can reliably assess memory, language ability, executive function and other traits in people with intellectual disability linked to autism.

A comprehensive atlas of gene expression by brain region could spur new research on autism.
