(a) Photomicrograph showing SMI-32-ir in the BNC at the bregma −3.8 level. See Paxinos and Watson (2007) for depictions of the exact borders of these nuclei at this level. See Figs. 3(c) and (d) for higher power photomicrographs of neurons in adjacent sections in the same brain. Scale bar = 200 μm. Additional abbreviations: BMp, posterior subdivision of the basomedial nucleus; LV, lateral ventricle. (b) SMI-32-ir in the somatosensory cortex. Note staining of PNs in three discrete layers (III, V, and VI). Scale bar = 100 μm.
