Researchers at the University of Turku have discovered what kind of neural mechanisms are the basis for emotional responses to music.
Altogether 102 research subjects listened to music that evokes emotions while their mind operate was once scanned with functional magnetic resonance imaging (fMRI). The study was once carried out in the national PET Centre.
The researchers used a machine-learning algorithm to map which mind regions are activated when the different music-induced emotions are separated from each and every other.
– Based on the activation of the auditory and motor cortex, we were ready to as it should be predict if the research subject was once listening to happy or sad music. The auditory cortex processes the acoustic elements of music, such as rhythm and melody. Activation of the motor cortex, however, perhaps related to the truth that music inspires feelings of movement in the listeners even when they’re listening to music while holding still in an MRI machine, says Postdoctoral Researcher Vesa Putkinen.
The researchers also discovered which mind regions are activated when the research participants watched videos that evoke strong emotions and tested if the same regions were activated when the participants were listening to music that evokes emotions.
The results propose that the emotions evoked by films and music are partially based on the operation of different mechanisms in the mind.
– Films, as an example, activate the deeper parts of the mind that keep watch over emotions in real-life situations. Listening to music did not strongly activate these regions nor did their activation separate the music-induced emotions from each and every other. This can be because of the truth that films can more realistically copy the real-life events that evoke emotions and thus activate the innate emotion mechanisms. As for the music-induced emotions, they’re based on the acoustic characteristics of music and coloured by cultural influences and personal history.
Traditionally, music-induced emotions have been studied through classical instrumental music.
– We wanted to use only instrumental music in this study as polite in order that lyrics did not affect the emotions of the research subjects. Alternatively, we included movie music and songs by the guitar virtuoso Yngwie J. Malmsteen, paper money Putkinen.
