1-way ANOVA with Tukey analysis of eccentricity. Geographic spots or locations were defined as in Figure 2A and Table 2. The data suggest that cells in the far periphery were more eccentric than those in the macula and mid-periphery. Also, cells in the macula were less eccentric than those in the mid-periphery.
