Figure 3. The Inactivation of PRR Causes Misreaching to Peripheral but Not Central Targets Similar to Optic Ataxia.

Figure 3

(A) Extrafoveal versus foveal reaches. The monkey reaches to the green circle. Under the extrafoveal condition, eyes are fixated on the red square while reaching. Under the foveal condition, eyes are not constrained.

(B) Sample hand and eye traces of 15 trials for a single target location in a typical inactivation (dark red/reach and light red/saccade) versus control session (dark black/reach and light black/saccade). Under the extrafoveal condition, the eyes are fixated on the center fixation target. Under the foveal condition, the eyes initially fixate at the center hand position, jump to the target location as soon as the target is presented, and stay until the hand reaches the target.

(C) The average reach amplitude (mean ± SEM) across all inactivation (red) versus control (black) trials. Trials for all six target locations were combined.
