Figure 3.

Tuning curves from two example cells in experiment 1 for the epochs after movement onset (a) (number of trials for each fixation position: left, n = 107; center, n = 81; right, n = 88) and preceding reward presentation (b) (left, n = 154; center, n = 144; right, n = 152). Firing rate is plotted against either retinocentric or nonretinocentric target position for each cell. Blue curves represent movements that began 10° left of center, red curves represent those beginning at the central fixation point, and green curves represent those beginning the point 10° right of center.
