Music and Emotion : The Neural Correlates of Music-Induced Positive Affect

Abstract: Listening to music is rated as one of the most pleasurable activities in human life and,in fact, listeners report the emotional impact of music to be one of the main motivatorsas to why they listen to music. This thesis focuses on the positive affective statesexperienced when listening to music and their underlying neural substrates. Despite thefact that research on the neural correlates of music-induced positive affect is arelatively recent undertaking our understanding has significantly improved during thelast decades. The aim of the current thesis is to give an overview of the neuralcorrelates of music-induced positive affect in healthy individuals. As such,psychophysiological, neuroimaging and electrophysiological studies are reviewed.Across studies the consistent involvement of brain regions, such as the orbitofrontalcortex, the striatum and the amygdala and left hemisphere frontal regions in response tomusic-induced positive affect has been found. These structures constitute an importantpart of the mesolimbocortical reward circuitry found to be involved in the processing ofa wide range of pleasures. The thesis also discusses conceptual and methodologicallimitations inherent in the studies reviewed. Understanding the nature and underlyingneural basis of music-induced positive affect is important because of the implications itmay have for psychological and physical wellbeing.
