Fig. 2: Both constrained and full models fit voxel responses.

A Distribution of R² values for full (pink) and constrained (blue) models. Distributions for both models were similar, with the constrained model R² median slightly but significantly higher (p = 7.4 × 10⁻¹¹, two-sided Wilcoxon rank-sum test). B R² values for the full model as a function of R² values for the constrained model. C R² values for constrained model as a function of pRF R². D R² values for the full model as a function of pRF R². E R² values for full model minus R² for a constrained model as a function of pRF R². F R² values for a full model minus R² for a constrained model as a function of pRF eccentricity. G pRF R² values as a function of pRF eccentricity. Solid lines in C–G indicate a running mean computed over 20 bins.
