(A) Representative ventral medulla section (interaural −3.30 mm, × 120) showing Fos-IR in the parapyramidal region in semi-restrained conscious rats exposed for 2 h either at room temperature or in the cold (4°C). (B) Increase in Fos-positive cells in the PPR induced by 2-h cold exposure. Each column represents the mean ± S.E.M. of Fos-positive cells/section (left plus right PPR) of four rats in each group. *P < 0.05 compared with Fos levels in rats semi-restrained at room temperature.
