Mapping aesthetic musical emotions in the brain

Area of Science:

• Neuroscience
• Affective Science
• Music Cognition

Background:

• Traditional neuroscience research often simplifies music's emotional impact into basic positive/negative or happy/sad categories.
• Music evokes a complex spectrum of emotions, including nuanced states like wonder, nostalgia, and tenderness, which are not fully explained by simple valence/arousal models.

Purpose of the Study:

• To investigate the neural correlates of a wider range of affective responses to music beyond simple dichotomies.
• To explore how different emotional dimensions (valence, arousal) map onto distinct brain activation patterns during music listening.

Main Methods:

• Functional neuroimaging (fMRI) was employed to measure brain activity.
• Parametric analyses were used, correlating brain activation with the intensity of subjectively reported emotions.
• Participants listened to music while experiencing a broad range of emotions.

Main Results:

• Positive emotions showed differential activation based on arousal: high-arousal (Wonder, Joy) engaged left striatum/insula; low-arousal (Nostalgia, Tenderness) engaged right striatum/orbitofrontal cortex.
• High-arousal emotions (Tension, Power, Joy) activated sensory/motor areas, while low-arousal emotions (Peacefulness, Nostalgia, Sadness) engaged ventromedial prefrontal cortex/hippocampus.
• Right parahippocampal cortex showed activation across most conditions, except for positive high-arousal emotions.

Conclusions:

• Music listening recruits distinct neural networks for different emotional states, involving reward, memory, self-reflective, and sensorimotor processes.
• The findings suggest a complex interplay of brain regions underlies the rich emotional experience of music.
• This differentiated neural recruitment provides a basis for understanding the unique affective power of music.
