Mutations in two genes linked to autism and intellectual disability boost the immune response and cause synapse dysfunction.

People with autism or autism traits may be especially vulnerable to brain aging and cognitive decline, two studies suggest.

A set of neurons connecting the prefrontal cortex and the thalamus helps regulate social interactions in mice.

Autistic men show a greater imbalance between excitatory and inhibitory signaling in the brain than autistic women do, which could explain sex differences in ‘camouflaging.’

A growing number of studies are revealing circuits that may underlie social challenges in autism — and how to fine-tune them.

The amygdala has long been a focus of autism research. But its exact role in the condition has been unclear.

Many genes in a brain region implicated in autism change expression patterns in late fetal development, depending on differences in neighboring DNA.

Several regions in the outer layer of the brain are thicker in children and young adults with autism than in their typical peers.

People with autism may have patterns of brain activity that are similar to those in typical people when interpreting social interactions.

Neurons in mice that lack an autism gene called CNTNAP2 do not differentiate well between social and nonsocial smells — an issue that seems to stem from haphazard neuronal firing.
