Group-average preferred spatial frequency (cycles/deg) for individual V1 segments.

Each polar angle bin is defined as 22.5° of angle centered at the labeled value (i.e., 11.25° of angle includes data between 0° and 22.5° of polar angle). 0° of angle is defined as at the right horizontal meridian of the visual field and angle increases counterclockwise around the visual field. Each eccentricity bin is defined as 1° of eccentricity centered at the labeled value (i.e., 2° eccentricity includes data between 1.5°–2.5° eccentricity). These values are derived from log-Gaussians fit to beta weights from the ‘combined’ stimuli condition (i.e., the average of the beta weights for each pinwheel-annulus stimulus pair. (XLSX)
