[The pressor zone in the caudal part of the ventral surface of the medulla oblongata].
The changes of the vessel resistance of the skeletal muscle and the small intestine perfused with constant blood flow, under electrical stimulation of the ventrolateral medulla were studied on artificially ventilated urethane-anesthetized cats. The stimulation of rostral ventrolateral medulla increased vessel resistance in both regions. The stimulation in a region 2 mm caudal the middle of the rootlets of the twelfth cranial nerves decreased the vessel resistance, but in a region 4 mm caudal the middle of the same rootlets increased the vessel resistance of the skeletal muscle and the small intestine.
