FIGURE 24

Number of labeled pyramidal neuron bodies in same-eye and opposite-eye ocular dominance columns (ODCs) of V1 after injection into a single ODC, 3-wk vs 24-wk monkey. The injected ODC is at zero on the x-axis, and neighboring ODCs are numbered in successive rows from the injected ODC. V1 of the 3-wk monkey had equivalent numbers of labeled neurons in same and opposite-eye ODCs within 4 rows from the injection site (t test, P = .15, comparing ODC 0 to ODC 1; 2 to 3). Fewer neurons were labeled by the transported tracer—in both same and opposite-eye ODCs—with increasing distance from the injected ODC. In the 24-wk monkey, greater numbers of labeled neurons in same-eye, and fewer in opposite-eye ODCs within 4-or-more rows from the injection site (t test, P = .03, comparing ODC 0 to ODC 1; 2 to 3). Means ± SD.
