Children who have repetitive behaviors, a core autism trait, may show particular patterns of brain activity as early as 1 year of age.

Autistic children aged 2 to 4 have about 15 percent more fluid between their skull and their brain than their typical peers do.

Administering a cholesterol drug alongside an antibiotic eases atypical behavior and restores the signaling balance in the brains of people with fragile X syndrome.

Specialized neurons called chandelier cells, which dampen brain signals, make unusually few connections in the brains of people with autism.

An inexpensive, noninvasive method can track social brain development in infants in low-resource countries.

A tiny fraction of the connections between brain regions can identify an individual.

A new technique transforms the previous broad-brush picture of a brain region into a pointillist masterpiece of neuronal subpopulations associated with specific activities.

Brain activity governing language can distinguish children with autism into distinct subgroups.

Babies eventually diagnosed with autism learn to detect speech sounds later than their typical peers do.

New open-source software helps scientists pinpoint where electrical signals are produced in the brain.
