Figure Legend:
Experiment 1. (A) Mean horizontal vergence velocity profiles over time to sinusoidal luminance gratings moving horizontally in opposite directions in the two eyes. Spatial frequency is denoted by grayscale coding of velocity traces; see the inset. Subject WG: Each trace is the mean response to 142–161 stimulus repetitions. Abscissa shows the time from the stimulus onset; horizontal dotted line marks zero velocity; horizontal thick black line beneath the traces indicates the response measurement window. (B–D) Semilog plots of VR amplitude against grating SF. Red filled symbols: horizontal VRs; blue open symbols: vertical VRs. (B) Subject BMS: diamonds, 274–292 trials per condition; (C) subject CQ: squares, 128–255 trials per condition; (D) subject WG: circles, 142–161 trials per condition. Color-coded horizontal lines above each graph show the 95% confidence intervals of the fits' peak locations. Color-coded vertical lines in the right lower corner of each graph show the mean amplitude (±SEM) of VRs orthogonal to the axis of stimulus motion (thinner lines) and version responses along the axis of stimulus motion (thicker lines). Since the calculation of these measures was done in exactly the same way as described in Materials and methods for the VRs along the axis of motion, the sign of version (and orthogonal vergence) responses is arbitrary. We therefore plot absolute values.
