Figure 1. Arrangement of the individual hexagons by rings and quadrants.

Figure 1

A. Superior nasal (SN), superior temporal (ST), inferior temporal (IT), inferior nasal (IN). Central hexagon (52) is excluded from any quadrant. For statistical analysis the quadrant distribution was flipped around the vertical axis for the left eyes.

B. Arrangement of concentric rings starting from central hexagon (52), which is the ring one and towards the periphery scaled with eccentricity to the ring six. Number in each hexagon represents individual hexagon numeration.
