Electric brain responses reveal gender differences in music processing

The present study investigates gender differences in the functional organization of the brain for music processing. In the language domain, males appear to have greater left hemisphere control than females. Despite some overlap of neural structures and processes for the perception of music and language, gender differences of musical functions have so far not been reported. Data sets of three previous music experiments with event-related brain potentials (ERPs) were pooled and re-analyzed. Results demonstrate that an electrophysiological correlate of music-syntactic processing (ERAN, or music-syntactic MMN) is generated bilaterally in females, and with right hemispheric predominance in males. The present findings indicate that gender differences for the analysis of auditory information are not restricted to processes in the linguistic domain such as syntax, semantics, and phonology.
