Changes in expression of phosphorylated cyclic adenosine monophosphate–response element–binding protein (pCREB) after intraperitoneal administration of midazolam in postnatal days 7 rats. A, B, and C (upper panels: ×8 magnification; lower panels: ×30 magnification) are photomicrographs of pCREB immunostaining in the hippocampal CA3 area from postnatal days 7 rats. D, E, and F (upper panels: ×8 magnification; lower panels: ×30 magnification) are those of pCREB immunostaining in the thalamus from postnatal days 7 rats. G and H show the number of pCREB-positive cells (mm2) in the hippocampal CA3 area and thalamus, respectively. MDZ = midazolam. ***P < 0.001. Data are derived from 12 slices in each group.
