Figure 5.

Effect of microstimulation applied shortly after both leftward (Lt) and rightward (Rt) saccades. a, Horizontal gain plotted against saccade number for leftward (left panel) and rightward (right panel) saccades, which show a marked decrease and increase in gain, respectively. b, The horizontal component of movement endpoints (relative to initial target location) of leftward and rightward saccades, both of which exhibit gradual rightward shifts in endpoints. On the ordinate, −10° and 10° indicate target positions to which the animal made leftward and rightward saccades, respectively. c, The vertical component of movement endpoints of leftward and rightward saccades, both of which show small, gradual upward shifts in endpoints.
