Conversely, when they were listening to music which did not produce a "chill", less dopamine was released. We examined dopamine release in the nucleus accumbens across multiple time scales, using complementary microdialysis and voltammetric methods during adaptive decision-making. And that helps animals (including people) change their behaviors in ways that will help them attain more of the rewarding item or experience. Most of the dopamine in your body is produced in the ventral tegmental area (VTA) of the brain, which is a main player in the brain's pleasure and reward signaling.
