A computer program called NeuronStitcher can quickly and accurately sew a series of brain scans into a three-dimensional rendering.

A brain scanner that simultaneously measures brain activity in two people holds promise for capturing social interactions and nonverbal communication.

Characterizing the interaction between brain networks that govern attention and reward may help classify subgroups of people with autism.

Patterns of gene expression in the brain vary dramatically between male and female mice — a finding that highlights the hazards of using only male mice to study complex disorders.

A miniature microscope made from cheap, ‘off-the-shelf’ parts can track firing neurons in the brains of freely moving mice.

An immune molecule that helps defend people from infection with viruses or bacteria may also keep brain activity in check, allowing people to be social.

A new drug that targets a molecule involved in learning reverses some cognitive difficulties in a mouse model of Rett syndrome.

Tiny pulses of blue light dampen the expression of inflammatory genes in microglia, and may cause unplanned effects when using optogenetics.

Mice that lack the Rett gene in a subset of neurons that activate neural circuits develop tremor and anxiety-like behaviors, two characteristics of the syndrome.

A new study casts brain cells called astrocytes as minor stars in Rett syndrome, a disorder that almost exclusively affects girls.
