Watching the sleeping brain watch us - sensory processing during sleep.
Presentation of auditory stimuli to sleeping subjects produced distinct fMRI activation patterns. Whereas pure tones activated auditory processing regions, subjects' names additionally activated language centers as well as the left amygdala and prefrontal cortex. These studies open the way for crucial studies of sleep-dependent cognitive processing.
