135 The Differences Between Females and Males in Music Perception: A Fundional Transcranial Doppler Study

Background: Several studies have focused: on the differences in music perception regarding hemispheric dominance and musical education, but to the best of our knowledge none of them investigated gender difference. The aim of our study was to determine the differences and lateralization of changes in mean blood flow velocity (MBFV) in the middle cerebral artery (MCA) during auditory stimulation between female and male listeners. Methods: Using transcranial Doppler (TCD) we assessed MBFV in 61 healthy right-handed subjects (41 female, and 20 male). First the left MCA was insonated and the subjects listened 2 minutes to a relaxing musical piece, after a pause the same was repeated with the right MCA. Time (T1 max) and amplitude (A1 max) of first maximum response of MBFV in MCA was measured as well as maximum amplitude (Amax) of MCA's MBFV and the time (Tmax) to obtain it. Mann-Withney-U test was used for statistical analysis. Results: Female listeners had shorter Tmax in the left MCA than in the right (p=0.002), while in males no difference was found. Male listeners had longer T1 max in the left MCA (p=0.003) and higher A1 max in the right MCA (p= 0.038) than female listeners. Also the Tmax in the left MCA was longer in the male than female listeners (0.013). However no difference was found in Amax in both MCAs between those two groups. Condusion: Both cerebral hemispheres are involved in music perception in both females and males and only slight differences by means of functional TCD were obtained Further studies involving larger groups are needed.
