A new study has found that listening to sounds such as music and noise has a significant effect on an individual`s moods and emotions, possibly as a result of brain dopamine regulation - a neurotransmitter strongly involved in emotional behaviour and mood regulation. The study was conducted by researchers from the Aarhus University in Denmark, and was published in the journal Neuroscience.
Say the researchers, Our results suggest that even a non-pharmacological intervention such as music might regulate mood and emotional responses at both the behavioural and neuronal level.The results showed that in participants with DRD2GG receptors the mood improved after music exposure, whereas in GT participant’s mood deteriorated after noise exposure.
Moreover, the music, as opposed to noise environment, decreased the striatal activity of GT subjects as well as the prefrontal activity of GG subjects while processing emotional faces. These findings suggest that genetic variability of dopamine receptors affects sound environment modulations of mood and emotion processing.
Importantly, this study encourages the search for personalised music-based interventions for the treatment of brain disorders associated with aberrant dopaminergic neuro transmission as well as abnormal mood and emotion-related brain activity.
