Monkeys missing the gene SHANK3 have too few neurons in the prefrontal cortex, a brain region involved in planning and social behavior.

Transcranial treatment may bolster memory in adults with autism, inflammatory molecule may alter an emotional brain region in newborns, and examining ants could yield insights into autism

Microscopic balls of brain and blood vessel cells mimic the barrier that protects the brain from foreign invaders.

Mice missing FMR1, the gene mutated in fragile X syndrome, have an atypical brain response to meeting an unfamiliar mouse.

Music therapy proves ineffective for autism, brain structures differ with 16p11.2 duplications and deletions, and mice missing NLGN3 may influence the sociability of their littermates.

Researchers have debuted two mouse models of autism made using the gene-editing tool CRISPR. Both strains lack one copy of CHD8, a gene with strong ties to autism.

New software transforms mouse brain scans into a virtual brain that scientists can manipulate.

Turning on a set of neurons that dampen brain activity improves social behavior in a mouse model of autism; turning off neurons that excite brain activity does the same thing.

Mice with an extra copy of UBE3A, a gene linked to autism, have learning problems and anxiety, and are prone to seizures and fine-motor problems.

A drug that keeps neurons bathed in the chemical messenger serotonin prevents social abnormalities in a mouse model of dup15q syndrome.
