Some neurons activate autism-linked genes when they fire, according to a new study.

Researchers have created the most complete macaque reference genome to date and used it to catalog genetic variation among hundreds of monkeys.

Altering a protein linked to Rett syndrome so that it cannot bind to a methylation tag in neurons results in Rett-like traits in mice.

Blood levels of PTEN protein and associated molecules could eventually help diagnose autism and other neurological conditions — and predict their outcomes.

A controversial idea about how cells compartmentalize their contents into droplets — like beads of oil in water — could be key to understanding autism, says Julie Forman-Kay.

Misaligned gene expression maps suggest that some autism-linked genes play distinct roles in mouse and human brains.

Muffling expression of an autism-linked gene in a key song-related area of the brain renders young zebra finches unable to learn songs from older birds.

Mice with a mutation in their mitochondrial DNA show altered brain activity, repetitive behaviors and reduced sociability, according to a new study.

Mutations that disrupt binding sites in RNA molecules may play a role in autism and a variety of psychiatric conditions, according to a new study.

A new tool enables researchers to create mosaic mutations in only some cells and then accurately identify which cells are affected.
