In summary, a substantial portion of the excitatory drive to vasomotor sympathetic preganglionic neurons originates from reticulospinal tonically active cells located in the RVLM. This interpretation does not exclude the possible contribution of other tonically active bulbospinal or propriospinal inputs in generating the vasomotor outflow but under usual anesthetic conditions it seems that these alternative inputs are simply insufficient to bring the vasomotor preganglionic neurons to their… CONTINUE READING
