Fig. 10. Photomicrographs and autoradiographic images of AChE staining (A, B), α7 mRNA (C–F), and [125I]α-BTX binding-site (G–J) distributions in the control and lesioned S1 of an animal 4 d after a unilateral, electrolytic lesion at postnatal day 6. Adjacent, tangential sections through the cortex at the level of layers IV (A, C, E, G, I) and VI (B, D, F, H, J). The primary barrel region (area withinarrowheads) and the five barrel rows (a–e) are indicated. A1, Auditory cortex; CPu, caudate putamen; PRh, perirhinal cortex. Scale bar, 1 mm.
