APS Annual Meeting at Experimental Biology

Respiratory Patterning: Within and Beyond the Breath

Symposium — Tuesday, April 27, 2021 — 4:00 PM - 5:30 PM — , Room APS-12
Respiration Section — Chair: Michael Harris — Co-Chair: Victoria Jensen

This symposium will focus on how the intrinsic properties of individual respiratory neurons, respiratory neuronal networks, as well as their neuromodulation under different physiological conditions, can generate alterations within and between the three phases of breathing: inspiration, post-inspiration and expiration. An important related topic is how, under changing conditions, the CNS recruits additional motor units (i.e. those innervating the intercostal and abdominal muscles) to adjust not only respiratory rhythm, but also tidal volume. This concept is then expanded to not only patterning within a respiratory cycle, but also patterning between series of breaths (i.e. the episode as a unit of modulation). Finally, this session will introduce novel methods of analysis to identify and quantify specific patterns of breathing (i.e. those that occur in different frequency domains), and be able to use this information in a predictive manner.
