| Research Abstract |
Process addictions including pathological gambling have many similarities with substance use disorders. To elucidate cognitive and neural bases of these conditions, functional neuroimaging studies applying reward anticipation or decision making tasks were conducted in subjects with pathological gambling. As results, subjects with pathological gambling showed decreased activity in a broad range of the reward system during reward anticipation tasks. In addition, the activation was associated with duration of illness, suggesting that the neural activity may serve as a clinical marker of pathological gambling.
