Single unit recordings were obtained from 103 precentral cortical cells whose activity was related to an alternate wrist flexion-extension task in monkeys. Although the task was carried out under different loads only a weak relationship between cortical cell firing rates and static force levels was observed for force in one direction. A large change in firing rate occurred, however, when direction of force shifted as a result of a change in the predominant activity between extensor and flexor… CONTINUE READING
