The same techniques that generate images of smoke, clouds and fantastic beasts in movies can render neurons and brain structures in fine-grained detail.

Eye-tracking studies cement monkeys’ promise for studying autism and related conditions.

A chemical that doctors use to create contrast on X-rays also yields clear images of neurons in the brains of living mice.

The drug mavoglurant has no effect on a brain circuit involved in social behavior in a mouse model of fragile X syndrome. That may explain its poor performance in people with the condition.

Mutations in the Rett syndrome gene MECP2 have different effects on subtypes of neurons.

The activity of the brain’s face detector, the fusiform gyrus, in response to faces is greater in adolescents with autism than it is in younger children with the condition.

Combining a brain imaging technique with a neuron stimulation method can reveal how activity at one site travels through neural networks in the brain.

A wireless miniature microscope lets researchers peer into the brains of mice as they run along a 25-foot track.

Five scientists describe the biggest challenges they face in solving sleep problems in people with autism.

Differences in sleep and circadian rhythm may distort the results of autism studies.
