To reach the dish on the table, the humanoid robot has to know in which direction to move the hand. A variance of the task allowed us to test whether the direction of reaching movements influenced the discharge of V6A reaching neurons. Monkeys were required to reach visual targets placed in different spatial locations while gazing at them. In other words, the animal performed reaching movements toward different spatial locations while maintaining the target of reaching under foveal control. We found that the direction of reaching strongly modulates the activity of V6A cells. An example of this behaviour is shown in Figure 8 [at right].
