Schematic overview of the orexinergic pathways involved in the descending control of sympathetic output to cardiovascular effectors. The contribution of Ox1R and Ox2R at each level is represented by the relative size of the Ox1R and Ox2R labels. This is a tentative representation only, reflecting the current stage of our knowledge. Abbreviations: Pa, paraventricular nucleus of the hypothalamus; RVLM, rostral ventrolateral medulla; RVMM, rostral ventromedial medulla (plus medullary raphe); Sol, solitary nucleus; SPN, sympathetic preganglionic neurons.
