Stroboscopic and interferometric analyses of the resulting phase-contrast disturbances of the respiratory rhythm revealed that carotid chemoafferent traffic was dynamically filtered centrally by a parallel bank of leaky integrators and differentiators, each being logically gated to the inspiratory or expiratory phase in a stop-and-go manner as follows: 1) carotid short-term potentiation of inspiratory drive was mediated by dual integrators that both shortened inspiration and augmented phrenic motor output cooperatively in long and short timescales; 2) carotid short-term depression of respiratory frequency was mediated by a (possibly pontine) integrator that lengthened expiration with a relatively long memory; and 3) carotid \u201cchemoreflex\u201d shortening of expiration was mediated by an occult fast integrator, which, together with carotid short-term depression, formed a differentiator. These effects were modulated anteriorly by integrators in the nucleus tractus solitarius that were \u201cauto-gated\u201d to, or recruited by, the carotid sinus nerve input. Such phase-selective and activity-dependent time-frequency filtering of carotid chemoafferent feedback in parallel neurological-neurodynamic central pathways may profoundly affect respiratory stability during hypoxia and sleep and could contribute to the dynamic optimization of the respiratory pattern and maintenance of homeostasis in health and in disease states. <\/jats:p>","DOI":"10.1152\/japplphysiol.00639.2002","type":"journal-article","created":{"date-parts":[[2015,3,3]],"date-time":"2015-03-03T20:44:02Z","timestamp":1425415442000},"page":"1213-1229","source":"Crossref","is-referenced-by-count":29,"title":["Integration-differentiation and gating of carotid afferent traffic that shapes the respiratory pattern"],"prefix":"10.1152","volume":"94","author":[{"given":"Daniel L.","family":"Young","sequence":"first","affiliation":[{"name":"Harvard-MIT Division of Health Sciences and Technology, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederick L.","family":"Eldridge","sequence":"additional","affiliation":[{"name":"Department of Cell and Molecular Physiology, University of North Carolina, Chapel Hill, North Carolina 27599"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chi-Sang","family":"Poon","sequence":"additional","affiliation":[{"name":"Harvard-MIT Division of Health Sciences and Technology, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"24","reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1152\/jappl.1979.46.4.843"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1970.sp009170"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1016\/0034-5687(71)90092-2"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1152\/jappl.1983.54.5.1195"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1152\/jappl.1982.52.4.863"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1996.sp021751"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1152\/ajpregu.1998.274.6.R1546"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1979.sp012766"},{"key":"B9","first-page":"475","author":"Cunningham DJC","year":"1986","journal-title":"Handbook of Physiology.
