This HDF5 file contains the numerical values shown in Figure 1.
(a) Circular square wave test grating (1 cycle/°) viewed normally (no lens). (b) The same grating viewed through the -10 dioptre cylindrical lens, with the lens axis aligned horizontally, …
(a) The distribution of preferred orientation in control animals exhibited an over representation of cardinal orientations. The dashed line shows the expected distribution if all orientations were …

The mean inter-ocular difference in preferred orientation (ΔOP) is significantly greater than 0 in both control (mean ΔOP = 11.8°, p < 0.001, two-tailed t-test) and cross-reared animals (mean ΔOP = …
The distributions of preferred temporal frequency for single units from control and cross-reared animals are not significantly different (p = 0.2, Kruskal-Wallis test).
The distributions of semi-saturation contrast (σ, see Equation 4) for single units from control and cross-reared animals are not significantly different (p = 0.81, Kruskal-Wallis test).
(a) Time course of the relative change in reflectance (∆R/R) during a trial, averaged over all pixels and all trials, measured with red (609 nm) and green (520 nm) light. The shaded region shows the …
This HDF5 file contains the numerical values shown in Figure 4.
(a) OP map, (c) OD map and (e) overlay of OD and OP contours for a control cat. (b) OP map, (d) OD map and (f) overlay of OD and OP contours for a cross-reared cat. While qualitatively the control …
This HDF5 file contains the numerical values shown in Figure 5.
The mean distributions of normalised orientation selectivity for all control and cross-reared hemispheres. Normalised orientation selectivity was calculated as the absolute value of each pixel in …
(a) Proportion of cortical area representing different orientations from binocular stimulation for all control hemispheres (colored lines), their mean (thin black line), and the best fitting sine …
(a) Pinwheel density relative to squared map wavelength was not significantly different between control and cross-reared animals, both being consistent with the theoretically predicted value of π …
This HDF5 file contains the numerical values shown in Figure 6.
(a) The distributions for control and cross-reared hemispheres are not significantly different (p = 0.36, two-sample Kruskal-Wallis test). For the quantification we used (see Materials and methods), …
The mean, normalised orientation selectivity in each of the five ocular dominance bins used to quantify pinwheel location relative to ocular dominance borders (see Materials and methods), averaged …
