Here's how classical music improves brain functions

A new study has revealed that listening to classical music modulates genes that are responsible for brain functions.

As per the University of Helsinki study, listening to classical music enhanced the activity of genes involved in dopamine secretion and transport, synaptic neurotransmission, learning and memory and down-regulated the genes mediating neurodegeneration.

Several of the up-regulated genes were known to be responsible for song learning and singing in songbirds, suggesting a common evolutionary background of sound perception across species.

Listening to music represents a complex cognitive function of the human brain, which is known to induce several neuronal and physiological changes. However, the molecular background underlying the effects of listening to music is largely unknown.

The study group has investigated how listening to classical music affected the gene expression profiles of both musically experienced and inexperienced participants. All the participants listened to W.A. Mozart's violin concert Nr 3, G-major, K.216 that lasts 20 minutes.

Listening to music enhanced the activity of genes involved in dopamine secretion and transport, synaptic function, learning and memory. One of the most up-regulated genes, synuclein-alpha (SNCA) is a known risk gene for Parkinson's disease that is located in the strongest linkage region of musical aptitude. SNCA is also known to contribute to song learning in songbirds.

Lead author Irma Jarvela said that the up-regulation of several genes that are known to be responsible for song learning and singing in songbirds suggest a shared evolutionary background of sound perception between vocalizing birds and humans.

The effect was only detectable in musically experienced participants, suggesting the importance of familiarity and experience in mediating music-induced effects, researchers remarked.

The findings give new information about the molecular genetic background of music perception and evolution, and may give further insights about the molecular mechanisms underlying music therapy.

The study appears in journal PeerJ.
