The strength and synchrony of brain waves appear to evolve differently in children with autism than in their neurotypical peers.

The brain’s sound-processing machinery may mature slowly in children with autism.
Delayed activation of brain areas governing speech could contribute to the language difficulties some people with autism experience.
Signals that relay sensations from nerves to the brain are abnormally strong in people with autism, a finding that may explain why some people with the disorder are overly sensitive to light, sound and touch.
Children missing a stretch of chromosome 16 known as 16p11.2 process sound a split second slower than typical children do. The findings suggest that genes encoded in the 16p11.2 region may underlie the hearing delay seen in some people with autism.
Male mice with a genetic variant linked to autism vocalize less in social situations than controls do during encounters with female mice. The findings help to characterize the effects of variants in the 16p11.2 chromosomal region.
A new device designed to conduct magneto-electroencephalography in children younger than 3 years is ideal for detecting early signs of autism, researchers reported 3 March in Frontiers in Human Neuroscience.
When exposed to irritating noises or images, children with autism show hypersensitivity in brain regions that process sensory information and emotions, according to a study published in November in the Journal of the American Academy of Child and Adolescent Psychiatry.
A difference in how auditory nerve fibers develop may explain why children with autism process sounds more slowly than typically developing children do. The result, published in September in Brain Research, also suggests that a widely used method for assessing nerve fiber structure may not be appropriate for autism research.
