Figure 6.

Similar adaptive shifts in endpoints elicited when both leftward and rightward saccades are coupled with microstimulation. a, Transfer of the induced adaptive change to saccades to target steps of various vectors. Data are from the same experiment shown in Figure 5 and shown in the same format as in Figure 2a. Two pairs of open and filled triangles indicate clusters of endpoints in prestimulation (red) and poststimulation (blue) session for saccades to 10° leftward and rightward target steps, respectively. b, Similarity in adaptive shifts in endpoint between leftward and rightward saccades. Summary of 10 experiments. Filled and open circles indicate experiments in monkey I and monkey M, respectively. Left, Shift direction (degrees) for rightward saccades is plotted against that for leftward saccades. For both ordinate and abscissa, 0, 90, 180, and 270 indicate right, up, left, and down, respectively. Right, Shift amplitude (degrees) for rightward saccades is plotted against that for leftward saccades.
