Axon projections of Nrg1-positive neurons in the hippocampus. A–C Expression of tdTomato in coronal brain slices at the positions of bregma − 1.7 mm A, − 0.82 mm B and − 3.16 mm C after injection of Cre-reporting AAV into the DG and Sub of 2-month-old Nrg1Cre/+ mice. Four weeks after AAV injection, the brain slices were collected and analyzed. Scale bar, 500 μm. D Summary of the projections of Nrg1-positive neurons in the DG and Sub of mouse hippocampus. DG: dentate gyrus; RSG: retrosplenial granular cortex; MF: mossy fiber; F: fornix; DF: dorsal fornix; Sub: subiculum; MM: mammillary nucleus
