Fig. 5.

Relationship between behavioral and BOLD anisotropies across visual fields. Mean behavioral anisotropy index is plotted against BOLD anisotropy index from the lower and upper visual fields. Each data point represents a group average from each cortical area (V1, V2, and V3). Dashed lines indicate the absence of radial-tangential anisotropy. Error bars indicate ±1 SE across 7 subjects. Horizontal error bars are offset vertically from each other to add visibility. There is only 1 behavioral index for each visual field. The corresponding (vertical) error bars are placed on the V1 symbols.
