The Brain

A new study pinpoints the genes and cell types that may underlie the atypical brain structure seen in people with genetic conditions linked to autism.

The brainstem controls such disparate functions as breathing, sensation and sleep — all of which can be altered in autism.

A growing number of studies are revealing circuits that may underlie social challenges in autism — and how to fine-tune them.

Most people with autism have motor difficulties, ranging from an atypical gait to problems with handwriting, but researchers still have much to learn about their causes and consequences.

About 6.5 percent of autistic people in the United States also have dyslipidemia, a condition characterized by abnormal lipids levels in the blood.

A new atlas lays bare how synapses, or the junctions between neurons, change from birth to old age in mice.

A computer program aligns mouse brain images with a reference brain atlas, helping researchers analyze neurons and their connections in a standardized way.

Nearly all genes with moderate to strong ties to autism are expressed in the developing amygdala; a few show altered expression in the amygdalae of autistic people.

Babies with telltale patterns of electrical activity in the brain have pronounced autism traits as toddlers.
