Sažetak
BACKGROUND: Recent studies have shown that the perception of musical information involves both cerebral hemispheres. The aim of our study was to determine the time course and lateralization of changes in mean blood flow velocity (MBFV) in the middle cerebral artery (MCA) during auditory stimulation. METHODS: Using transcranial Doppler (TCD) we assessed MBFV in 61 healthy right-handed subjects (20 male and 41 female) with or without musical education. 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. Half of the subjects were asked to relax during listening to music (passive group), the other half was asked to pay attention to the musical sounds (active group). RESULTS: The following statistically significant differences (p<0.05) were found. Female listeners reached first maximum of MBFV in the right MCA faster than male listeners, however male listeners had higher first maximum of MBFV in the right MCA and higher absolute maximum of MBFV in left MCA than female listeners. The first maximum appeared faster in the right MCA in passive listeners than in active listeners. Listeners without musical education reached habituation in the right MCA faster than musically educated listeners. CONCLUSION: Our data suggest that music perception requires bilateral activation of cerebral hemispheres. Lateralization and changes of MBFV differ among males and females, active or passive listeners and those with or without musical education.
