| Abstract | Dopamine plays a pivotal role in realizing reward-oriented behavior. Dopamine neurons transmit prediction error signals that reflect the gap between reward expectation and actual reward outcome. Here, I give an overview on the functions of the dopamine system based on studies of animal psychology and neurophysiology and introduce my recent study on impulsivity control disorder in Parkinson's disease patients, in which a theory and methods of behavioral economics were applied. |
