A delayed brain response to viewing faces may predict lags in social-skill development in autistic people.

A new protocol aims to help researchers include more autistic people — especially those who are minimally verbal or have intellectual disability — in imaging studies.

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

A glowing protein tracks serotonin levels and location in the brains of living mice and could yield clues to the neurotransmitter’s role in autism.

Mice missing a copy of MAGEL2 have trouble discerning between a familiar mouse and an unfamiliar one; treating them with the social hormone vasopressin reverses this deficit.

Children with dup15q syndrome may have telltale patterns of brain activity during sleep and get less non-REM sleep than neurotypical children do.

Looking at eyes, noses and mouths may prompt slower recognition in the brains of autistic people than in those of non-autistic people.

Minimally verbal autistic people do not differentiate the sound of their own name from that of a stranger, according to a new EEG study.

Contrary to previous results, the blood pressure drug did not uniformly improve autism traits in a new clinical trial.

Hearing difficulties and autism often overlap, exacerbating autism traits and complicating diagnoses.
