The ventral tegmental area is located in the midbrain and helps regulate learning and reinforcement in the brain's reward system. It produces dopamine, a neurotransmitter that plays an important role in positive feelings, such as receiving a reward.In one experiment, macaques were allowed to choose multiple times between two images\u2014a star or a ball, for example. This told which of the two visual stimuli they tended to naturally prefer. In a second experiment, the ventral tegmental area was stimulated with mild electrical currents whenever they chose the initially nonpreferred image. This quickly changed their preference. In the end macaques' altered preference has been manip...","url":"http:\/\/76xkbxgntgu2uwxb.onion\/threads\/58"}]}
