V1 alternation modulated by boundary contours. A, Response time courses for four different configurations of MBC stimuli having rivaling centers. The gray curves are individual L–R time courses (n = 25) calculated from the V1 region corresponding to the central disk. The red curves are the average time courses (±SEM). V1 activation clearly showed biases toward the eye viewing a boundary contour. B, An OD pattern was revealed in the contrast map comparing left-eye (LE) and right-eye (RE) MBC conditions (the same data as in A). C, V1 retinotopic representation of a circular contour (line width 0.1°) confirms that the eye dominance in B was within the disk representation.
