To examine the effect of hypoxia confined to the ventrolateral medulla we microinjected NaCN into the cat medulla (1.0 mm below the ventral surface) unilaterally and investigated cardio-respiratory changes. We studied anesthetized artificially ventilated animals and measured the electrical activity of phrenic and cervical sympathetic nerves and blood(More)
Respiratory activity and airway tone can be significantly affected by perturbations confined to superficial areas of the ventrolateral surface of the medulla (VMS). It is not clear which neuromediators are responsible for these changes. Neurotensin (NT), a tridecapeptide, fulfills many of the criteria required for a neurotransmitter or a neuromodulator. In(More)
