Subcortical control of human reaching?

这个项目将测试一个关于人脑如何产生视觉引导行为的激进的新假说。传统的想法认为，肢体运动的视觉运动控制仅发生在大脑皮层内。然而，该项目团队最近对视觉引导的肌肉活动极快的观察结果强烈表明，人脑通过更原始的中脑和脑干结构控制伸展运动。该项目的假设挑战了长期以来关于人脑功能组织的想法，并可能对康复、工业和体育中的人机界面设计以及训练方案的设计产生广泛的影响。

This project will test a radical new hypothesis about how the human brain generates visually guided behaviour. Conventional thinking assumes that visuomotor control of limb movements occurs exclusively within the cerebral cortex. However, the project team’s recent observations of extremely rapid visually guided muscle activity strongly imply that the human brain controls reaching movements via more primitive midbrain and brainstem structures. The project’s hypotheses challenge long-standing ideas about the functional organisation of the human brain and may have wide-ranging implications for the design of human-machine interfaces as well as training protocols in rehabilitation, industry, and sport.
