title: Differential effects of awakening from REM and NONREM sleep on dichotic listening performance as a function of handedness.
abstract: Fourteen right-handed and fourteen left-handed males were wakened from REM and NONREM sleep and tested on the dichotic listening test with verbal stimuli. For right-handers there was a significant right ear advantage (REA) only after REM wakenings, which was equal in magnitude to the REA obtained during waking. Left-handers showed significant REA after both wakening conditions, as well as during waking. These results are interpreted in view of the data suggesting REM-related right hemisphere activation and the role of the right hemisphere in regulating bihemispheric arousal levels.
