Figure 1.
Spatial extent of the SVZ and planes along which brains were sectioned (A–F) and stereotactic coordinates and injection sites (G–J). A–E, The SVZ is indicated by red in each section. The planes of other sections relative to the one shown are indicated by lowercase letters in each section. A, Coronal section at the level of the septal nuclei. B, Coronal section at the level of rostrodorsal hippocampi. C, Lateral sagittal section at the level of the striatum. D, Medial sagittal section at the level of the septal nuclei and the RMS. E, Horizontal section at the level of the striatum. F, Anterolateral view of the whole brain showing the five planes of section. G–J, Sites of injection shown in sagittal planes and coronal planes are depicted on the left and right, respectively. G, Olfactory bulb injection. Virus was placed at a depth of 0.8 mm from the center of the dorsal surface of the olfactory bulb. H, Rostral injection; 2.0 mm anterior, 0.9 mm lateral to the bregma at a depth of 2.5 mm. Arrow in the coronal plane indicates the vertical limb of the RMS. I, Middle injection; 0.7 mm anterior, 1.9 mm lateral to the bregma at a depth of 1.9 mm. J, Caudal injection; 0.7 mm posterior, 2.1 mm lateral to the bregma at a depth of 2.0 mm.
