V1 injections, χ2 = 1988;p < 0.001; V4 injections, DY, χ2 = 14,073; p < 0.001; FB, χ2 = 14073;p < 0.001.
Multinomial ANOVA was used to test differences in SLN% across visual areas. χ2 and p values are provided. Analysis of labeling resulting from V1 injection was performed using values obtained in case M71 (both hemispheres) in which SLN% values were obtained in all the projecting areas (Table 1). Dyes, sides, and areas were treated as between-group factors. After V4 injections, the analyses were performed on values obtained from each dye separately, and subjects and areas were treated as between-group factors. Statistical levels of significance are indicated for the planned comparisons of SLN% between pairs of area (NS, Not significant; *p < 0.01; **p < 0.001). These comparisons are used to rank pairs of areas (higher, >; lower, <; same level, =. Ex: Area V2 is lower than area V3.). Because of a small number of labeled cells in V1 after V4 injections (range, 0–46 cells per animal; Table 1) the power of the statistical test is greatly reduced, and when planned comparisons did not reach the significance level (as for example V1 vs V3; i.e., 100 vs 60 SLN%), we cannot affirm if it is real or attributable to the small sample size. Paired comparisons with V1 have been omitted in this table (NA).
