Effect of subthreshold FEF microstimulation on response discriminability for aligned and misaligned visual stimulus conditions. (A) (Left) During aligned stimulus conditions, the visual stimulus was positioned within the RF (dotted circle) at the end point of the saccade that could be evoked from the stimulation site (red arrow). (Right) Late-period discriminability is shown for stimulation (red) and control (black) conditions for the population of neurons exhibiting reliable tuning for aligned stimuli. Conventions are as described in Fig. 2C. (B) (Left) During misaligned stimulus conditions, the visual stimulus was positioned within the RF (dotted circle) at a location that was spatially offset from the end point of the saccade that could be evoked from the stimulation site (red arrow). (Right) Late-period discriminability values for stimulation (red) and control (black) conditions for the population of neurons exhibiting reliable tuning for misaligned stimuli. Conventions are as described in Fig. 2C.
