Passively listening to music engages which neural system?

• A. Endogenous opioid system
• B. Dopaminergic reward system
• C. Visual cortex
• D. Spinal cord reflexes

Answer: (A)

Passively listening to music engages the brain’s reward circuitry, with the dopaminergic reward system playing a central role. As you hear melodies, the brain makes predictions about upcoming notes and resolutions, and the anticipation and fulfillment of those predictions trigger dopamine release along the mesolimbic pathway (from the ventral tegmental area to the nucleus accumbens). This dopamine signaling underpins the pleasure, motivation to continue listening, and emotional arousal that many people experience with music, even without any active task. The endogenous opioid system also contributes to hedonic experience, but the dopaminergic reward system best explains the core rewarding aspect of listening. The visual cortex isn’t primarily involved in processing sound, and spinal cord reflexes pertain to basic motor responses, not the perceptual-emotional experience of music.
