运动学策略编码在经典的直线达到运动皮层区域是非常简单和一致的科目,尽管复杂的肌肉骨骼动力学。然而,随着任务变得更具挑战性,不同的有意识策略可能会被用来提高感知行为表现。我们发现,额外的空间信息出现在单个神经元和群体代码的猴子背前运动皮层障碍阻碍时,直接到达路径。运动规划的神经相关性在受试者之间以与使用不同策略以优化任务完成一致的方式变化。这些不同的规划策略表现在神经群体代码中包含的信息的时间和强度上。
The kinematic strategy encoded in motor cortical areas for classic straight-line reaching is remarkably simple and consistent across subjects, despite the complicated musculoskeletal dynamics that are involved. As tasks become more challenging, however, different conscious strategies may be utilized to improve perceived behavioral performance. We discovered that additional spatial information appeared both in single neurons and in the population code of monkey dorsal premotor cortex when obstacles impeded direct reach paths. The neural correlate of movement planning varied between subjects in a manner consistent with the use of different strategies to optimize task completion. These distinct planning strategies were manifested in the timing and strength of the information contained in the neural population code.
