A new imaging genetics study, led by the Professor Elvira Brattico from Aarhus University and conducted in two Italian hospitals in cooperation with the University of Helsinki (Finland), has found the first evidence that the influence of music and noise on affective behaviour and brain psychology are associated with genetically determined dopamine functionality.
The study discovered that a functional variation in dopamine D2 receptor gene modulates the influence of music as opposed to noise on mood states and emotion-related prefrontal and striatal brain activity. Results of the study showed mood improvement after listening to music in subjects with GG genotype and mood deterioration after listening to noise in subjects with GT genotype.
The director of the study Professor Elvira Brattico says: “This study represents the first use of the imaging genetics approach in the field of music and sounds in general. We are really excited about our results because they suggest that even a non-pharmacological intervention such as music, might regulate mood and emotional responses at both the behavioural and neuronal level.”
