Neural correlates of impairments in music emotion processing in major depressive disorder: Evidenced from an event-related potential study

BACKGROUND Patients with major depressive disorder (MDD) commonly exhibit widespread cognitive impairments. Music, as a complex auditory stimulus with relatively high ecological validity, can be utilized to investigate brain information processing mechanisms. Event-related potentials (ERPs) are well-suited for capturing the temporal dynamics of neural processing across successive cognitive stages. However, the number of systematic ERPs studies examining multi-stage musical information processing
