Abstract (in Japanese) (See Japanese page) 
(in English) We analyzed spike activities of the monkey anterior intraparietal area (AIP) to reveal how the brain represents information related to hand manipulation. During the hand manipulation task, many AIP neurons respond
selectivity to the 3D shape, orientation and size of the objects to be grasped and/or the hand configuration to grasp them. Here, we calculated mutual information (MI) between spike frequency of single neurons and various clusters of 6 objects, and examined how MI changed dependent on different task periods (i.e., fixation, reaching and grasping) for each clustering. MI took peak values in different periods dependent on clustering types: For some neurons, MI for rough clustering had the peaks in the fixation period while MI for fine clustering had the peaks in the reaching or grasping period. This suggests that AIP neurons may represent information relevant to the hand manipulation in a hierarchical manner, that is, different grains of information in different periods.
