Signs & Symptoms

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

Two studies published in the past two months provide new clues to when and how the cerebellum contributes to autism.

A monkey-sized jacket embedded with motion sensors — similar to technology used to animate creatures in movies — is helping researchers develop the common marmoset as a model for studying human social behavior.

Stimulating the vagus nerve may normalize the brain response to sound in a rat model of Rett syndrome. It may also improve rats’ behavioral response to certain speech sounds.

Adding motor and sensory data boosts the accuracy of Research Domain Criteria — a broad research framework adopted by the U.S. National Institute of Mental Health — for predicting autism.

Mice with different genetic backgrounds have distinct behavioral profiles — and that may muddle findings from mouse research.

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

Tracking how roundworms crawl has enabled scientists to determine that many autism genes are involved in sensory processing and learning.

An autonomous robotic ‘rat’ may offer novel insights into the social responses of its warm-blooded counterparts.
