We have analyzed neuronal activities of the monkey anterior intraparietal area (AIP) to reveal how the brain represents information related to hand manipulation. Here, we calculated mutual information (MI) between activities of 98 single neurons and various clusters of 6 objects, and examined how MI changed dependent on different task periods (i.e., fixation, reach and hold). We found that the different types of neurons (i.e., visual-, motorand visuomotor-neurons) had significant information in different task periods. Moreover, we summed up MI for the populations of each type of neurons, which show temporal relationship among the information processings in different types of neurons. The result of this analysis gives us a novel clue to understand the information stream in the parietal area in sensory-motor control. |
