1. The GABA-B receptor agonists baclofen and 3-aminopropylphosphinic acid (3-APPi) have antitussive activity in the cat and guinea pig. The purpose of this study was to investigate the sites of action of these GABA-B receptor agonists to inhibit the cough reflex. 2. Single intracerebroventricular (i.c.v.) cannulas were placed in the lateral ventricles of(More)
1. GABAB agonists inhibit neuronal processes which are important in the pathogenesis of airway disease, such as bronchospasm. Cough is a prominent symptom of pulmonary disease, but the effects of GABAB agonists on this airway reflex are unknown. Experiments were conducted to determine the antitussive effect of GABAB receptor agonists in comparison to the(More)
Experiments were conducted to study the effect of the opioid, codeine, on different components of the cough motor pattern. Midcollicular decerebrate cats were paralyzed and artificially ventilated by a pump triggered by the phrenic neurogram. Inspiratory (phrenic) and expiratory (cranial iliohypogastric) neurograms were recorded. Fictive cough was produced(More)
