A method that maps signaling molecules in the brain may help researchers home in on areas where seizures originate.

A new technique gives researchers a window into the constellation of neurons that fire as zebrafish larvae swim in a dish.

A new method lets researchers spy on cells as they gain and lose chemical tags on their DNA.

Using a sugar alcohol found in fruit, researchers have concocted a new chemical cocktail for making brains transparent.

A new version of the popular gene-editing tool CRISPR gives scientists the ability to both edit and activate genes using a single protein.

A new tool that charts large DNA duplications and deletions in single cells may help researchers assess the variants’ contribution to autism.

A new questionnaire provides a standardized measure that allows researchers to reliably track repetitive and restricted behaviors over time.

A head-mounted device tracks both blood flow and electrical activity in the brains of moving rats.

A new computer program predicts the effects of mutations in regions of the genome that control gene expression. Researchers can use the tool, called DeepBind, to gauge whether autism-linked mutations might block the genetic landing strips for regulatory proteins.

A new device lets researchers wirelessly stimulate the brains of rodents as they explore their cages, and can deliver drugs at the same time. Its use could identify brain circuits that mediate autism-like behaviors.
