examined after warm (33° C) and cold (10° C) ambient exposures. Fos expression was
examined with use of immunohistochemical method and the number of Fos-positive neurons
In each nucleus was quantitatively analyzed. When rats were exposed to cold ambient,
significant number of Fos-positive neurons was found in the lateral septal nucleus (LS),
preoptic hypothalamic area (POA), parvocallular paraventricular hypothalamic nucleus …
