FOS and Seizure: The results revealed that DBS in the MS decreased the number of c‐Fos+ cells in the CA1 from (107.08 ± 12.19) to (38.25 ± 11.35) (Figure 2C, F (3) = 1.04, p < 0.01, n = 4), CA3 from (131.23 ± 20.56) to (45.33 ± 11.98) (Figure 2D, F (3) = 1.82, p < 0.05, n = 4), and DG from (59.10 ± 9.01) to (29.63 ± 6.31) (Figure 2E, F (3) = 2.9, p < 0.05, n = 4) after KA‐induced seizure compared with those without DBS.
