Abstract

The results showed that Fos-like immunoreactive (FLI) neurons were distributed throughout nucleus tractus solitarius, area postema, rostral ventrolateral medulla and nucleus raphe pallidus, and the number of FLI was increased with the elevation of ISP. Furthermore, perfusing the carotid sinus with Ado at a given ISP markedly increased the FLI in the above regions.
