APS Annual Meeting at Experimental Biology

Above and Beyond the CPG: Influence of Higher Brain Centers on Breathing

Nonfunded Featured Topic — Friday, April 30, 2021 — 2:00 PM - 3:30 PM — , Room APS-12
Respiration Section — Chair: George Richerson — Co-Chair: Kevin J Cummings

While the essential neurocircuitry responsible for basic respiratory rhythmogenesis and patterning resides in the brainstem, new data are emerging indicating that regions of the midbrain and forebrain can powerfully modulate breathing under a variety of conditions. For example, several hypothalamic nuclei, including the lateral, perifornical, and paraventricular hypothalamus contribute to eupnea and the hypoxic and hypercapnic ventilatory responses. The midbrain periaqueductal gray can also modulate breathing in response to visual, auditory, and emotional cues. Dr. George Richerson from University of Iowa will be the featured speaker and will present data showing that amygdala is key for the apnea that contributes to sudden unexpected death in epilepsy (SUDEP). This Featured Topic is open to all research that focuses on novel neurophysiological mechanisms by which higher brain centers control breathing in normal and pathophysiological conditions.
