By tickling the whiskers of mice, and recording how they respond, UCLA researchers may be closer to understanding why many children with autism cover their ears when they hear loud sounds or can’t tolerate scratchy wool sweaters.

Scientists report in the June 12 issue of the Journal of Neuroscience that mice genetically engineered to mimic a type of autism in humans, fragile X syndrome, are unable to adapt to, or tune out, repeated stimulation to
