| Research Abstract |
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.
