Introduction:Read notes & play piano = very complex
motor taskNotereading:
Visual spatial domain program with infoMusical syntax MUSIC!
Introduction:Rehearse skills with
practiceMENTAL IMAGERY
PerformanceMOTOR IMAGERY:
mental stimulation of action in *Visuomotor system
Motor Imagery & Motor ActionSimilar timingInvolve same muscles in corticospinal
excitabilityProven in fMRI studies (Fadiga, 1999)
Experimental Task:Aim: Investigate cortical network during
performance & imagery of music12 music academy students Use an electronic keyboard that produced
no soundsPlay the right hand part of a Bartok pieceBefore fMRI, subject practiced until
familiar
Performance: Imagery:Subjects played
the presented music with their RH on the keyboard
Instructed to read the notes & imagine themselves playing the presented music
Not moving their hands
Watched by videocamera
After fMRI-sessionCompleted a questionnaire about their
sensations during the conditionsRated the difficulty of the piano pieceFilled out the “Vividness of Mental Imagery
Questionnaire”
Results:Both: bilateral
frontoparietal network, precuneus, medial of BA 40
Performance: contralateral PMC, posterior parietal cortex bilaterally
Imagery: bilaterally extrastriate cortex
Discussion:Comparing pixels, imagery= smallerThe differences in accordance with prior studiesSMA & PMC activated predominantly in left
hemisphereReflects the roles: motor execution
Posterior parietal cortex visuomotor transformation
Precuneus working memory processesCerebellum crucial for motor imagery;
motor/rhythm timing & coordinationmany more structures
Conclusion:Performance & imagery: FRONTOPARIETAL NETWORK:
motor imagery & visuomotor associationOCCIPITAL NETWORK:
notereadingGreater fMRI activation in performance
At posterior parietal areas & Primary sensorimotor cortices
Reflects higher level of visuomotor integrationWhole activated network- rhythms, pitch
discrimination
Strengths:Very precise & controlledStudied a lot of different networks in the
brain
Limitations:None?
My Opinions:Very interesting paper since I’m also a pianist
Would there be a difference in RH- Dominant players and LH- Dominant players?
What about those gifted children?6 yrs old who can play &compose like Mozart?http://www.youtube.com/watch?
