Amano Inc visual field coverage maps
Group <t>coverage</t> surface‐volumetric differences in noiseless data and simulations to check for CNR and pRF size effects. Bootstrapped (50 repetitions with replacement) effect size (Cohen's d) representation of the surface‐volume difference in <t>field</t> of view coverage depending on the different analyses. The comparisons were paired. A. Noiseless data in volumetric versus its projection to the surface. Only voxels with more than 50% variance explained were included. B. Simulations to examine CNR effects. pRF size between the two conditions was kept constant, while the CNR differences were increased from left to right. With no CNR difference, the Cohen's d <t>map</t> equals a random field (leftmost panel). With CNR differences, a clear bias toward higher coverage in the fovea and lower coverage in the periphery appears (center and right panels). C. Simulations to examine pRF size effects. CNR was equated in the two conditions, but the pRF size for the surface condition was increased from left to right. With increasing difference a similar bias occurs, however, the bias in the foveal compared to peripheral areas was less pronounced.
