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.

An ultra-thin and flexible electrode array can record brain signals without disturbing the underlying tissue.

Fetal mice that have too many neurons grow to show social deficits and repetitive behaviors. The finding, reported 11 December in Cell Reports, debuts a mouse model of autism that’s based on a biological abnormality seen in some people with the disorder.

Mice missing PTEN, a strong autism candidate gene, in a subtype of inhibitory neurons in one part of the brain show signaling abnormalities and social deficits. Researchers presented the unpublished work yesterday at the 2014 Society for Neuroscience annual meeting in Washington, D.C.

Children with autism show different patterns of brain activity during everyday gestures and movements than controls do, suggest unpublished results presented today at the 2014 Society for Neuroscience annual meeting in Washington, D.C.

Mice modeling autism have trouble integrating different kinds of sensory information such as sight, sound and touch. A study published 31 July in Neuron reports that an imbalance between signals that calm neurons and those that excite them leads to these sensory problems.

A “beautiful” new study traces a complex repetitive behavior in a mouse model of autism to a subset of neurons in one brain region.
