Musical talent is due to genetic peculiarities, the research of the Academy of Finland has shown. Many genes are involved here. In particular, some are responsible for the development of the inner ear and for the neurocognitive processing of sounds, reports The Times of India.
The perception of music begins with special hair cells in the inner ear. They transmit sounds as electronic signals along the sound path directly into the auditory cortex of the brain. There the sounds are recognized. Moreover, the process of processing music affects the areas of the brain associated with emotions, learning, memory.
Scientists have studied the genome of 767 people from 76 families who were able to distinguish the height of the tone, the duration of sounds and the sound schemes themselves in the melody. In their genome, single nucleotide polymorphisms were sought. The explicit connection with musical abilities was fixed relative to the chromosome 3, which is located not far from the gene GATA2. This gene regulates cochlear hair cells.
But the most accurate data were obtained from the study of 4 chromosomes with five genes - PCHD7, PDGFRA, KCTD8, CHRNA9 and PHOX2B. All of them affect the development of the inner ear and are expressed in the hippocampus or almond-shaped gland.
Of greatest interest is the area next to the PCDH7 gene, which manifests itself in the cochlear and almond complexes (tonsils - the emotional center of the brain).
