Conclusion On the basis of our studies it is apparent that RVMM in the rat is a unique and functionally important cardiovascular control region that is functionally quite different from RVLM. The presence of multiple cardiovascular control regions, each with unique functional characteristics, raises numerous fundamental questions about the complexities of cardiovascular control under a variety of behavioral, physiological, and pathophysiological conditions.

The dense projection from the region of the rostral ventromedial PAG to the autonomic part of the PGi implicates these PAG neurons in regulation of autonomic activities. Physiological studies are underway to examine whether these neurons influence peripheral autonomic function. Preliminary results reveal that electrical stimulation of the rostral ventromedial PAG does not have a significant effect on peripheral blood pressure. However, electrical stimulation of this area of the midbrain results in a sharp increase in respiratory activity (unpublished observations).
