The genetic basis of musical orientation: the neurobiology of music is related to the behavior associated with instinct

Music is a social interaction between individuals - lullabies help to bond maternal love and singing or playing music increases the relationship of a group. Research on neurobiology of musical perceptions and production can lead to the formation of brain pathways that influence the behavior associated with instinct. This is a finding made in a recent Finnish study. This research has given new information about the genetic foundations of musical aptitude.

In the study of the University of Helsinki and Sibelius Academy, Henlsinki, the basis of neurobiology of music in the evolution and human communication ability has been evaluated by using candidate genes. associated with previous studies on cognitive function and social cohesion. The data include 343 family members from 19 family lines in Finland with at least some professional musicians and / or amateur musicians active. Music orientation has been evaluated through 3 music contests: contest of auditory structure ability and Carl Seashore's sub-timetable and sub-tests. In addition, participants had to complete a blood sample test and a stressful computerized test was compiled from research topics for 12 years. Part of these multiple choice questions is designed to identify creative music functions: the ability to compose music, improvisation and music editing.

In this study, the high scores on music in the competition are stringed with the ability to create music (p <.0001), to be able to compose, improvise and improve music must be gifted. music. Creativity is a multi-factor genetic quality associated with a complex network formed by a number of genes and environments. For the first time, we have found that the creative function in music has a strong genetic component (h2 = 84: the ability to compose h2 = 40: arranging music h2 = 46: improvisation h2 = 62) in generations of Finnish people. In addition, inheritance characteristics play an important role in music aptitude.

To elucidate the basis of the neurobiology of music in human evolution and communication, the researchers demonstrated the association of the AVPR1A genotype, gene variants associated with sound aptitude. music.In previous studies, the gene AVPR1A and its homologous genes have created social and emotional action characteristics, including the bond between two people and the role of raising children . The results have shown that the neurobiology of consciousness and music production constitutes a brain pathway that influences instinctive behavior.

'Music is a way of social interaction among individuals, ' said Master Liisa Ukkola. 'Darwin pointed out that singing is used to attract heterosexuals, lullabies are also used to bind children to their parents and singing and playing music together raises the relationship. between a group. It is therefore possible to prove the hypothesis that the creativity in music and the ability to perceive music is linked to a certain range of social skills related to human awareness, like the taste. tha and the human-to-human binding relationship with AVPR1A. For the first time we can point out at the molecular level that musical perceptiveness has influence. '

This study belongs to a larger research project in which people learn about the biology of musical talent. The research leader is Professor Irma Jarvela. The main investigator is Master Liisa Ukkola, Professor Paivi Onkamo as data analyst, musician Pirre Raijas and professor Kai Karma who are experts in music aptitude. This study is published in Plos ONE.
