Summary: Interaction between auditory areas of the brain and the reward system drive pleasure when we listen to music.

Communication between the brain’s auditory and reward circuits is the reason why humans find music rewarding, according to new research published in Journal of Neuroscience. Despite no obvious biological benefits, humans love music. Neuroimaging studies highlight similarities between how the brain’s reward circuits process music and other rewards like food, money, and alcohol. Yet neuroimaging studies are correlational by nature.
In a new study, Mas-Herrero et al. sought to nail down the causal role of this circuitry by using non-invasive brain stimulation. A group of pop music fans listened to a set of pop songs while the research team measured their brain activity with fMRI. Before the scan, the team indirectly excited or inhibited the brain’s reward circuit with transcranial magnetic stimulation.
Exciting the reward circuit prior to hearing music increased the pleasure participants felt when listening to the songs, while inhibiting it decreased pleasure. These induced pleasure changes were linked to changes in activity in the nucleus accumbens, a key region of the reward circuit.
The participants with the greatest difference in pleasure also showed the greatest difference in synchronized activity between auditory and reward regions. These results indicate interactions between auditory and reward regions drive the pleasure we feel when listening to music.

* 4 Brain Chemicals That Make You Happy *
So then, what’s the real cause of our happiness? What makes us feel sensations of happiness, closeness, and joy? Brain chemicals! There are four primary chemicals that can drive the positive emotions you feel throughout the day:
> dopamine, oxytocin, serotonin, and endorphins (sometimes referred to as D.O.S.E.).
By understanding how these chemicals work on a basic level, we can better decide for ourselves whether the latest trends will be helping or hurting our happiness. Think of this as your introduction or field guide to what these chemicals are and how they affect your daily happiness.
- Dopamine - The (good & bad) habit former. An incredible tool when used appropriately!
- Oxytocin - The hugging drug or “love hormone.” Oxytocin makes us social and builds relationships with trust and loving feelings.
- Serotonin - The “leadership hormone.” Heavily related to pride, loyalty, and status.
- Endorphins - The natural painkiller. The runner’s high!...

Music = joy. My nucleus accumbens must be pretty robust to hold up after so many workouts.
