Fig. 4. The HCN4 expressions in the hippocampus of the normal and epileptic animal groups following SE. HCN4 immunoreactivities are rarely detected in all hippocampal regions, whereas its expression is observed in some interneurons (arrows in panels A2-A4). However, the immunoreactivities of HCN4 in the hippocampus following SE are unchanged depending on the time course after pilocarpine treatment (B1-D4). Bar = 280 μm (panels A1, B1, C1, and D1), 50 μm (panels A2-A4, B2-B4, C2-C4, and D2-D4). Quantitative analyses of HCN4 immunoreactivity in the normal and epileptic hippocampi following SE (E, mean ± S.E.M).
