Abstract
The evolution during learning of the relationships between neuronal activities of areas 4 and 5 and a self-initiated elbow flexion were studied. Two monkeys ( Macaca speciosa) were trained to stop a flexion movement in a given angular sector in order to obtain a reward. A screen prevented the monkey from seeing its rotating forearm, and the terminal position of the movement did not take place. In area 4, cells were found to be mainly linked to the movement. In area 5, cells were observed having an activity closely related to that of area 4, but there were also other cells whose activity was related to taking the reward. During a training session some cells of areas 4 and 5 showed an increase in their probability of discharge at the beginning of movement. An increase in the probability of movement in relation to the bursts of area 5 cells' activity was also noted.
