(A) V4 population averaged V4 firing rate for stimulus jerked (by 0.3°) away from fixation (blue line and shading) or toward fixation (red line and shading). Shaded area indicates ±SE. After 300 ms, the stimulus was jerked back to the original position.
(B) Firing rate modulation between jerk-toward and -away conditions (Jerktoward − Jerkaway/Jerktoward + Jerkaway) for each neuron for time windows of 50 ms to 150 ms after jerk time (transient response). The distribution did only slightly deviate from a distribution centered on zero.
(C) Same as in (B), but for time windows of 150 ms to 250 ms after the jerk time. Distribution deviated more significantly with enhanced V4 firing rate for jerk away from fixation point.
