The male offspring of mice subjected to stress during pregnancy can transmit the effects to their own male pups.

A new study of nearly 6,000 pairs of twins suggests that the three core traits of autism are inherited separately, and to varying degrees, both in individuals with autism and in the general population.

Mice lacking a gene that regulates an important signaling pathway in the central nervous system have severe autism-like social deficits, including little interest in nurturing their offspring and problems with learning and memory.

A protein that regulates the development of serotonin-producing neurons in the brain is associated with autism.

Methylation marks were thought to be permanent features of the genome, but a new study challenges that idea.

Boys who have autism-like social deficits at 2 years of age retain about the same level of social impairment when they reach age 20.

Two new studies suggest that people with autism don’t all have trouble detecting the motion of people and animals. What they do struggle with is picking up social information from bodies in motion.

Neurons in a mouse model of fragile X syndrome make more connections during a critical period in development compared with controls, but are slower to respond to signals.

Probiotic bacteria alleviate stress in healthy mice and modify the expression of receptors for a chemical messenger that inhibits signaling in the brain.

A new atlas of gene expression patterns in the adult mouse brain shows how thousands of genes are turned on in specific layers of the cortex.
