A potential new gene therapy delivered via a single injection mimics ratios of proteins normally found in cells.

Activating certain receptors in the amygdala — a treatment that runs counter to a leading theory of what causes the condition — can reverse some traits in rats.

Social memory, which may be altered in autism, depends on serotonin-sensitive neurons that send signals from the medial septum to the hippocampus.

Jolting a bundle of nerve fibers deep in the brain restores learning and memory in mice with mutations of the autism-linked gene CDKL5.

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

Mice missing a copy of the autism-linked gene NRXN1 appear to perceive some time intervals as shorter than control mice do, according to a new study.

Intranasal oxytocin may spur new neuron growth and changes in social behavior after a few weeks.

Mutations in POGZ, a gene strongly linked to autism, lead to a signaling imbalance in multiple brain regions in mice, according to two new studies.

Mice that model 22q11.2 deletion syndrome lack social memory, but that trait can be reversed using a drug that targets the flow of potassium ions in neurons.
