pianists

Introduction• Music performance: ability to read musical
notes and play an instrument simultaneously– Complex motor task– Requires rapid and effective transformation and
processing of visual information into complex movements
– Takes years of practice
Introduction• Looked at brain activation during musical
performance and during musical imagery in trained music students
• Purpose: – to investigate the cortical network which mediates
music performance compared to music imagery using functional magnetic resonance imaging (fMRI)
Subjects• 12 students from the Cologne School of Music– 10 female, 2 male (mean age: 26.6 years)
• Principal instrument: piano• Average total musical training: 18.4 years• Average practice time: 22 hours/week• All right handed
Experimental Task• Used a piano keyboard while in fMRI– No metal parts in keyboard (made no sound)
• Experimental music:– Short piano piece called “Triolak” by Bela Bartok
• Only right hand notes of music piece were shown on a computer screen
Experimental Task• Baseline: scan in fMRI, no task• Music Performance Condition: – Played presented piece with right hand on keyboard
• Music Imagery Condition: – Read music with hand off keyboard– Instructed to imagine themselves playing the piece– Monitored to ensure no hand movement
Results
Music Performance minus Baseline Music Imagery minus Baseline
Results• Fronto-parietal cortical
network activated:– Primary sensorimotor cortex– Posterior parietal cortex
• More activation during music performance condition (left) than music imagery condition (right)
Discussion• Left Primary Sensorimotor Cortex– Greater activation during music performance than
in music imagery– Reflects motor execution
Discussion• Bilateral Posterior Parietal Cortex– Greater activation during music performance– Integrates sensory information and processes
coordination of body movements within space– Mainly mediates visuomotor transformation
• Higher activation during performance suggests greater level of visuomotor integration required during motor execution
Strengths and Limitations• Strengths:– Good visuals– Analyzed many different brain structures that
appear to work together during music performance
• Limitations:– Few participants, mostly female– All from same school
Opinion• Overall interesting paper• Confusing– Methods could have been explained better
• For Future Studies:– Look at students learning to play piano to see if
same brain regions are activated
Summary• Greater activation in the left primary
sensorimotor cortex and bilateral posterior parietal cortex during music performance
• Greater level of visuomotor integration required during motor execution compared to mental stimulation
