Startled fish help sound out sensory overload in autism

by  /  8 June 2015

There is some evidence that neural habituation — the process by which neurons get used to sensory stimuli — goes awry in autism. Mutant fish may help us understand the sensory sensitivities that often accompany the disorder, says Alan Packer.

Signaling imbalance skews sensory responses in autism mice

by  /  11 August 2014

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.
