在灵长类动物中,前皮层参与运动的感觉指导。腹侧前皮层中的许多神经元对手臂或手臂附近的空间中的视觉刺激有反应。当手臂移动时,发现这些视觉接收场会移动,但在眼睛移动时不会移动。也就是说,它们以手臂为中心,而不是自发性的坐标。因此,它们提供了人体附近空间的表示,这可能对触及的视觉控制有用。
In primates, the premotor cortex is involved in the sensory guidance of movement. Many neurons in ventral premotor cortex respond to visual stimuli in the space adjacent to the hand or arm. These visual receptive fields were found to move when the arm moved but not when the eye moved; that is, they are in arm-centered, not retinocentric, coordinates. Thus, they provide a representation of space near the body that may be useful for the visual control of reaching.
