The timing of treatment is crucial for conditions related to autism — and more so for some conditions than for others.

Mice that lack a segment of chromosome 22 — a mutation associated with autism — have unusually sparse connections between brain regions.

A new technique leads to neuron cultures of consistent quality, enabling scientists to study how autism mutations alter neurons.

Two imaging techniques together reveal architectural features of the brains of preterm infants.

A top autism gene called SCN2A plays a role at neuronal connections into adulthood, offering hope for treating mutations after infancy.

Mice missing TAOK2, a gene in a segment of chromosome 16 linked to autism, have big brains, immature neuronal junctions and asocial behavior.

The male-dominated sex bias in autism is reversed in a related syndrome, a researcher’s gender could influence her study’s outcome, and an award-nominated ad featuring a young man with autism draws criticism.

A pruning protein reshapes neurons, culture should be a consideration in trials of autism treatments, and another U.S. state adds autism to the list of indications for medical cannabis.

Deleting KCTD13, a gene in the autism risk region 16p11.2, has little effect on brain or head size in mice — contradicting results from a 2012 zebrafish study.

A trio of drugs eases repetitive behaviors in mice by activating a brain region involved in motor control.
