Association of harm avoidance with dopamine D2/3 receptor availability in striatal subdivisions: a high resolution PET study.

abstract：:The present study examined lateralized event-related potentials (L-ERPs) associated with movement preparation and execution. In a response precuing task that involved hand and foot movements a precue conveyed either information about side and effector, side alone, or no information. Advance movement preparation was in...
