Music may activate genes for learning, memory

London: Playing music by professional musicians can enhance the activity of genes involved in motor functions learning and memory, a new study has found.

“The findings provide a valuable background for molecular studies of music perception and evolution, and music therapy,” said lead researcher Irma Jarvela from the University of Helsinki.

Music performance is known to induce structural and functional changes to the human brain and enhance cognition. However, the molecular mechanisms underlying music performance have been so far unexplored.

The researchers investigated the effect of music performance (in a two hour concert) on the gene expression profiles of professional musicians from Tapiola Sinfonietta (a professional orchestra) and Sibelius-Academy (a music university).

Playing music enhanced the activity of genes involved in dopaminergic neurotransmission, motor function, learning and memory. Some of the up-regulated genes like SNCA, FOS and DUSP1 are known to contribute to song perception and production in songbirds suggesting a potential evolutionary conservation in molecular mechanisms related to sound production across species.

In addition, several of the up-regulated genes are known to be involved in biological pathways like calcium ion homeostasis and iron ion homeostasis that are essential for neuronal function, survival and neuroprotection, the researchers said.
