Figure 4.

Comparison of callosal patches and ipsilateral eye domains. (A) Size of callosal patches demonstrated with intracortical injections of tracers and ipsilateral eye domains demonstrated with intraocular injections of WGA-HRP in different groups of rats (N = 7 per group). Mean sizes (and SEM) were calculated by measuring the area of labeled regions in thresholded versions of the labeling patterns demonstrated in tangential sections. (B) Comparison of the number (mean ± SEM) of ipsilateral eye domains and callosal patches within the CS. (C) Percentage of the surface area of CS that is occupied by ipsilateral eye domains and callosal patches. No significance was found when the size of patches, number of patches and the percentage of the CS occupied by the patches were compared between the 2 groups (P > 0.01).
