Untersuchung von Emotion mit Musik: eine funktionell-bildgebende Studie

Zusammenfassung

Die vorliegende Studie nutzt Musik zur Induktion von Emotion und funktionelle Magnetresonanztomographie (fMRI), um neurale Korrelate emotionaler Verarbeitung zu untersuchen. Das Hören von Musik, die als „angenehm” eingestuft wird, aktiviert die Larynxrepräsentation im Rolandischen Operculum der rechten Hemisphäre. Die Larynx ist Quelle der Stimmgebung und involviert in die Produktion von Melodie, Rhythmus und emotionaler Anfärbung vokalen Timbres. Diese Aktivierung der Larynxrepräsentation erinnert an die Aktivierung prämotorischer Areale während der Beobachtung von Greifhandlungen und deutet darauf hin, dass der Mechanismus der Perzeptions-Aktions-Vermittlung, der bereits für die visuelle Modalität beschrieben wurde, ebenfalls in der auditorischen Modalität existiert.

Abstract

The present study uses music as a tool to induce emotion, and functional magnet resonance imaging (fMRI) to determine neural correlates of emotion processing. We found that listening to pleasant music activated the larynx representation in the rolandic operculum. The larynx is the source of vocal sound, and involved in the production of melody, rhythm, and emotional modulation of the vocal timbre during vocalization. The activation of the larynx is reminiscent of the activation of premotor areas during the observation of grasping movements and might indicate that a system for the perception-action mediation which has been reported for the visual domain also exists in the auditory domain.
