Figure 6.

SK2 subunit mRNA expression in the postnatal rat brain. X-ray images of sagittal (A,C,E–G,I,K) and horizontal (B,D,H,J,L) sections at postnatal stages P1, P3, P6, P12, and P24 showing strong SK2 hybridization signals in the olfactory system, cerebral cortex (Cx), hippocampus (Hi), and cerebellum (Cb). For details on the distribution see Table5. Control sections (K,L) were hybridized in the presence of 100-fold excess cold oligonucleotide, showing a uniformly low, nonspecific labeling. For abbreviations see list. Scale bar = 4 mm.
