This resulted in a paradoxical inspiratory-related narrowing of the upper airway. Stimulation of the trigeminal ethmoidal nerve (EN5; 20 Hz, 100 \u03bcs, 0.5\u20132 V) evoked a diving response, which included a reflex apnea, glottal constriction, and bradycardia. After strychnine administration, this pattern was converted to a maintained phrenic nerve discharge and a reduced glottal constriction that was interrupted intermittently by transient abductions. The onset of firing of postinspiratory neurons shifted from early expiration into neural inspiration in the presence of strychnine, but neurons maintained their tonic activation during EN5 stimulation, as observed during control. Inspiratory neurons that were hyperpolarized by EN5 stimulation in control conditions were powerfully excited after loss of glycinergic inhibition. Thus the integrity of glycinergic inhibition within the pontomedullary respiratory network is critical for the coordination of cranial and spinal motor outflows during eupnea but also for protective reflex regulation of the upper airway. <\/jats:p>","DOI":"10.1152\/ajpregu.00502.2001","type":"journal-article","created":{"date-parts":[[2015,3,3]],"date-time":"2015-03-03T20:24:04Z","timestamp":1425414244000},"page":"R999-R1005","source":"Crossref","is-referenced-by-count":19,"title":["Trigeminal reflex regulation of the glottis depends on  central glycinergic inhibition in the rat"],"prefix":"10.1152","volume":"282","author":[{"given":"Mathias","family":"Dutschmann","sequence":"first","affiliation":[{"name":"Department of Animal Physiology, University of T\u00fcbingen, Auf der Morgenstelle 28, 72076 T\u00fcbingen, Germany; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julian F.
