Cardiac activity could reveal autism’s physiology and confirm a hunch many clinicians share: that people with autism experience great stress.

Sleeping zebrafish show two patterns of neuronal activity that are analogous to those in people.

Sleep problems may contribute to autism’s underlying biology — a connection that scientists can study in animal models.

Mikle South spends his days teaching classes, studying the relationship between anxiety and autism, and coping with living in a conservative state.

Researchers have engineered two generations of monkeys with mutations in SHANK3, a top autism gene. The first generation shows traits reminiscent of the condition.

Autistic children may be more likely than their unaffected siblings to carry mutations in genes linked to sleep.

Depression may show up in children with autism in an unusual way — most commonly as insomnia and restlessness.

Heightened sensory perception in toddlers with autism may predict sleep problems at around age 7.
