Topic: action inhibition

How actions are regulated based on environmental changes is a fundamental neurobiological question. A key component of action regulation is action inhibition, which when abnormal contributes to various neuropsychiatric disorders. We explored the mechanism of action regulation by recruiting healthy adults (n=15, ages 21-42) to perform reaches towards targets presented on a computer screen using a joystick. The experiment includes: decision-making task, in which subjects were instructed to reach towards one target or freely choose between two targets; stop-signal task, in which a stop signal app
