Figure 6.
Shows a summary for results for the effects of binocular rivalry and the visuospatial working memory tasks upon the VOR.24 (a) Plots of each subject's individual asymmetry index (ie, degree of nystagmus suppression) and handedness inventory score. Right handers showed a positive asymmetry index except for two subjects who were retrained left handers in both the motion binocular rivalry condition (diamonds) and visuospatial task (squares). In contrast, all left-handed subjects and the two retrained right-handed subjects had a negative VORTC asymmetry index. (b and c) Plots of the exponential grand averages for the eye velocity for right- and left-handed subjects. (b) When a control visual stimulus was presented the VOR was symmetrical following either rightward or leftward rotations (overlapping black and grey curves). (c) The VOR following the viewing of motion rivalry is shown. Note that in right-handed subjects the VOR was supressed following rightward rotation (grey curve), whereas in left-handed subjects the VOR was supressed following leftward rotations (black curve).
