Anatomy (T1), pre-training HVF map, pre-training V1 pRFs, and resulting visual-field coverage maps (maximum coverage) for pre-training and post-training V1 pRFs shown for 3 CB patients. The pRF method was used to estimate the position and size of the visual-field area that best explained each voxel’s visually-evoked response. The initial (pre-training) HVF map was used to define the blind-field border and determine whether each single pRF covered blind-field regions or solely intact-field regions with preserved HVF sensitivity. Single black dots on the coverage maps indicates the preferred center of each V1 pRFs.
