Histology. (A–C) Location and extent of the retrosplenial cortex (RSC) lesions for each of the three cohorts. The cases with the largest (pale grey) and smallest (dark grey) cortical lesions are depicted on a series of coronal sections The numbers refer to the approximate distance, in mm, of each section caudal to bregma [67]. (D) Photomicrographs from a representative lesion (top two rows) and a surgical sham case (bottom two rows) from groups RSC2 and Sham2. Scale bars represent 200 μm.
