Activation of caudal brainstem cell groups during the exercise pressor reflex in the cat as elucidated by...

Cell groups of the caudal brainstem were labeled with 2-[14C]deoxyglucose during the pressor response evoked by contraction of hindlimb muscles (exercise pressor reflex). The nuclear groups which were labeled in excess of control levels included: the lateral reticular nucleus, the inferior olive (medial accessory olive), and the lateral tegmental field (adjacent to the lateral reticular nucleus).
