Abstract
The sympathetic efferent pathway projects to the sympathetic ganglia and the adrenal medulla. In this study, we examined centrally administered corticotropin-releasing factor (CRF)-induced neuronal activation of noradrenergic postganglionic neurons in several kinds of the sympathetic ganglia (superior cervical, stellate and celiac ganglia) in anesthetized rats. CRF significantly increased c-Fos expression in the celiac and stellate ganglia, with more pronounced effect on the celiac ganglion. On the other hand, CRF had no effect on c-Fos expression in the superior cervical ganglion even at a higher dose. These results suggest that brain CRF selectively regulates neuronal activity of each sympathetic ganglion.
