enjoyable music activates a complex network involving the auditory cortex (the brain’s sound processing center) and two deeper brain regions: the bed nucleus of the stria terminalis (BNST) and the nucleus accumbens (NAc). These areas are part of the brain’s reward circuit, which plays a crucial role in mood regulation and pleasure.

The BNST-NAc circuit, sometimes referred to as part of the ‘extended amygdala,’ underscores the close relationship between this circuit and the amygdala, a central structure in emotional information processing,” Sun explains. “This study reveals that music induces triple-time locking of neural oscillations in the cortical-BNST-NAc circuit through auditory synchronization.”

Interestingly, the study found that even patients who were initially unresponsive to music could benefit from a technique called auditory entrainment. By incorporating specific sound frequencies into the music, researchers were able to “tune” the patients’ brains to be more receptive to the mood-boosting effects of music
