A unique study of brain activity in the cerebral cortex of epilepsy patients found there was a robust response to sound during sleep that largely mirrored the brain s response during wakefulness.
A study of the cerebral cortex discovered there is a robust response to sound during sleep that largely mirrored the brain's response during wakefulness. However, differences in brain waves that help the brain understand sound and anticipate what comes next is missing during sleep.
The new findings may help researchers understand how to use sound to improve memory during sleep and how much unconscious people are able to process auditory information.
