Individual brain-frequency responses to self-selected music

Area of Science:

• Cognitive Neuroscience
• Neurophysiology
• Auditory Perception

Background:

• Music elicits diverse emotional and cognitive responses, making brain reactivity to music a key area in cognitive neuroscience.
• Individual music preferences may influence how music affects the brain, necessitating an examination of common versus individual effects.

Purpose of the Study:

• To investigate common brain responses to music listening, even when individuals select their own preferred music.
• To compare music-induced brain activity with responses to a standardized tactile stimulation and a resting baseline.

Main Methods:

• Electroencephalogram (EEG) was recorded from 18 participants under four conditions: favorite relaxing music, favorite stimulating music, tactile foot stimulation, and rest.
• Analysis focused on changes in alpha and beta frequency bands, particularly in parietal and occipital brain regions.

Main Results:

• Significant alpha band responses (desynchronization followed by synchronization, or variations thereof) were observed in most subjects during music and tactile stimulation compared to rest.
• Increased beta activity was noted during activating music and tactile stimulation.
• Substantial interindividual differences in brain response patterns were found, despite comparable subjective emotional experiences and standardized tactile stimulation.

Conclusions:

• Brain reactivity to music exhibits significant individual variability.
• Future research should consider individual characteristics when examining brain responses to music.
• Both auditory (music) and somatosensory (tactile) stimuli can elicit comparable, yet individually distinct, neurophysiological responses.
