It is well known that music can influence our emotions. Research on mind-wandering has revealed that our emotional state can influence the valence of thought content and the prevalence of mind-wandering. Recent behavioural studies have suggested that music can modulate mind-wandering. However, the neural mechanisms to support the claims are unknown. This thesis aim was to explore how music can modulate mind-wandering by reviewing functional neuroimaging studies on the topic. The findings suggest that music induces mind-wandering as it engages the default mode network in a similar fashion that resting does. Music-induced activity from the orbitofrontal cortex and the posterior cingulate cortex seems to be a good neural indicator for mind-wandering content that has a negative valence.
