Summary
When reaching to grasp an object, we often move our
arm and orient our gaze together. How are these move-
ments coordinated? To investigate this question, we
studied neuronal activity in the dorsal premotor area
(PMd) and the medial intraparietal area (area MIP) of
two monkeys while systematically varying the starting
position of the hand and eye during reaching. PMd
neurons encoded the relative position of the target,
