In order to determine brain structures involved in processing of rhythm and melody, cortical DC-potentials were recorded from the scalp of 19 professional musicians during perception and imagination of rhythms and during analytical, creative and mnesric melodie tasks. For the rhythm tasks, subjects listened to simple or complex rhythms or to temporally unstructured sustained tones. Subsequently, either imagination of the rhythm perceived previously or no specifie cognitive task was assigned. For the melodie tasks, subjects listened to a sequence of four notes and subsequently were either to reverse the sequence or to compose a new continuation. In the third melodie task, the initial segment of a weJJ-known melody was presented and had to be continued. During acoustic stimulation, abilateral increase in brain activity predominantly over frontal and parietal brain regions occured in all tasks, irrespectively from the acoustical material presented. Imagination of rhythms yielded a significant activarion over posterior temporal regions of both hemispheres. Mental reversal of a melody caused the most pronounced activation, especially over parietal areas, probably due to visualization as a cognitive strategy. The creative task caused the lowest brain activation and elicited an unexpecred lateralization to the left, though we expected creativity to be a right hemispheric holistic-synthetic process. The only task which yielded a right-hemispheric lateralization was the mnestic task, supporting the view of right temporal structures involved in long term storage of music.
