Precision of receptive field location and discrepancy of orientation selectivity. (a) Location of receptive field centres mapped through the contralateral (filled circles and solid line) and ipsilateral (open circles and dotted line) eyes corresponding to 11 recording sites in V1 across the representation of the contralateral optic disc, N, nasal. (b) Difference in horizontal receptive field position (scatter) and difference in direction/orientation selectivity of the receptive fields for the contralateral and ipsilateral eye, for 123 recording sites. (c,d ) Representations of the receptive field response in the space domain, for the centres marked by arrows in (a), based on the single-unit responses to eight different directions The ellipse in the contralateral eye represents the optic disc position. Spike rate for each eye is colour-coded (right: colour scale).
