Dissociation of extra-retinal inputs to an MT neuron. A) PSTHs in response to a 2 s stimulus presentation for five of nine simulated depths in the RM condition (for clarity, data for ±0.5° and ±1.5° are not shown). One column of PSTHs is shown for each starting phase of simulated observer motion. Gray traces represent retinal image velocity, with peaks and troughs representing motion in the preferred and anti-preferred directions, respectively. B) Responses of the same neuron in the MP condition. Note that responses to near stimuli are accentuated, while responses to far stimuli are suppressed relative to the RM condition. C) Responses in the HO condition are very similar to those seen in the RM condition. D) Responses in the EO condition are very similar to those in the MP condition. E) Depth tuning curves for each of the four stimulus conditions: MP (black), RM (blue), HO (green), and EO (orange). Average firing rate over the 2s stimulus epoch is plotted as a function of simulated depth. Error bars represent SEs.
