Nicotine stimulates the expression of cFos protein in the parvocellular paraventricular nucleus and brainstem catecholaminergic regions.


The rapid secretion of ACTH in response to nicotine is mediated by a central mechanism involving brainstem catecholaminergic regions. To identify specific brainstem regions involved in activating the hypothalamo-pituitary-adrenal axis and other areas of the brain by iv nicotine, immunocytochemical detection of cFos protein was used as a marker for neuronal… (More)
