The number of c-Fos–immunopositive cells in the medial preoptic area (MPOA) decreased in sevoflurane-treated dams on the day of parturition. (A) Immunohistochemical staining for c-Fos in the MPOA (control dams: n = 5; sevoflurane-treated dams: n = 5). Scale bars: 250 μm. (B) Quantification of the immunohistochemical staining. ***P < 0.001 (t test).
