Fig. 5.
Many hippocampal interneurons expressing α7 nACh mRNA contain CCK immunoreactivity. (A, A’) Low magnification of epi-fluorescence (A) and bright field (A’) views of cellular expression of α7 nACh mRNA (A) and CCK immunoreactivity (A’). Frames B, B’, C and C’ correspond to higher magnification views of areas delineated in panel A. Large arrows indicate examples of neurons co-expressing α7 nACh mRNA and CCK immunoreactivity. Small arrows in B, B’, C and C’ indicate examples of neurons expressing either α7 nACh mRNA or CCK. Scale bar shown in B’ represents 180 μm for A and A’; 590 μm for B, B’, C and C’.
