TITLE:

CAUSAL ROLE OF THE RIGHT POSTERIOR PARIETAL CORTEX OVER AFFECTIVE VALENCE RATINGS ELICITED BY DANCE AND MUSIC: A VIRTUAL LESION APPROACH

PAGES: 40
BIG AREA: Outra
AREA: Multidisciplinar
SUMMARY:

Understanding the neural underpinnings of aesthetic experiences, particularly in music and dance, remains a complex yet compelling area of research. Previous neuroimaging and repetitive transcranial magnetic stimulation (rTMS) studies suggest the right posterior parietal cortex (r-PPC) involvement in affective valence perception judgments of aesthetic stimuli. However, methodological limitations have raised concerns about some of these results. This study aimed to replicate and extend the original findings by applying continuous theta burst stimulation (cTBS) instead of the traditional rTMS inhibition paradigm to test the possible causal role of r-PPC in mediating affective valence ratings (AVR) elicited by stimuli combining dance and music. We examined the influence of three auditory stimuli and cTBS stimulation protocol on ratings of affective valence elicited by a video showing a dance performance. Seventeen participants watched a short video of a continuous contemporary dance sequence, segmented into 30-second blocks, each paired with one of three randomly assigned auditory conditions: classical music, techno music, or human breathing sounds. They continuously provided valence ratings of the video after two experimental interventions: a) an active cTBS stimulation over the r-PPC, and b) a sham stimulation over the vertex. In accordance with the replicated study, we observed that ratings were more positive after active cTBS than after sham intervention for all auditory conditions. Moreover, the inclusion of classical music always elicited more positive ratings than other auditory stimuli. These findings underscore the causal role of inhibition of the r-PPC in eliciting more positive affective ratings by stimuli combining dance and music. Still, the specific role of dance movements in eliciting affective responses remains unclear.
