| Abstract(in English) | To elucidate how the brain constructs different muscle activities for manipulating various tools with different dynamics, a monkey was trained to extend and flex its forearm around the elbow joint against two different viscosity force fields. During the movements, electromyographic activities (EMGs) of the biceps and the triceps as well as simple spike (SS) discharges of cerebellar Purkinje cells (Pcells) were recorded. Temporal patterns of EMGs were successfully reconstructed from the weighted linear summation of temporal patterns of SS recorded from 30 Pcells. The estimated delays from SS to EMG were 26ms to 79ms, suggesting SSs can construct the difference of EMGs for different tools. The weights on SSs for reproducing EMGs were suggested to be different for two different force fields. |
