neural representation of action categories and object manipulations

本研究的目的是通过记录行为猴子的神经活动来研究高级运动区中的多个动作或操作的分类信息。我们检测了猴子补充运动区和前补充运动区的神经活动，以研究神经系统如何处理涉及双侧使用手臂的多个动作所产生的编码16个运动序列。我们首先发现，在这两个领域，这种行为需求导致了基于属性的代表个人运动行为，反映功能（行动）或解剖（右/左臂）属性。 动作通常根据以体轴为中心的参考框架（旋后或旋前）来表示，而与使用的手臂无关。 我们建议，二维基于属性的序列表示提供了一个强大的和有效的手段处理多个行为序列。

The aim of this study is how categorical information of multiple actions or operations in higher-ordered motor areas by recoding neural activities from behaving monkeys, We examined neuronal activity in the supplementary and pre-supplementary motor areas of monkeys to investigate how the nervous system deals with the coding 16 motor sequences resulting from multiple actions involving bilateral use of the arms. We first found in both areas that this behavioral demand resulted in attribute-based representation of individual motor acts, reflecting functional (action) or anatomical (right/left arm) attributes. Actions were frequently represented according to a body-axis centered reference frame (supination or pronation) irrespective of the arm to be used. We propose that the two-dimensional attribute-based sequence representation provides a robust and efficient means of processing multiple behavioral sequences.
