A new study suggests that hyperarousal in the brain’s motor cortex might help explain the origins of Restless Leg Syndrome (RLS), which has long remained one of the least understood sleep disorders. An estimated 10 percent of American adults experience RLS — which triggers an overwhelming urge to move the legs while at rest and …
