Example neuronal and muscular behavioral in response to breathing, cough and swallow (3). Fictive cough was elicited by stimulation of the superior laryngeal nerve. Swallow was initiated by transient infusion of water into the pharynx. The top 16 traces are of neurons recorded simultaneously in the caudal medulla. The traces represent nerve spike histograms of extracellulary recorded neuron action potentials. The neurons were labeled according to their respiratory related activity: I – inspiratory, E – expiratory, E/IE – phase spanning expiratory-to-inspiratory, NRM- non-respiratory modulated. The neurons were further classified according to: AUG – augmenting, increasing action potential frequency over the activity phase, DEC – decrementing decreasing action potential frequency over the activity phase. The bottom 4 traces moving-time averaged electroneurogram activity from the following nerves: PHR - phrenic nerve, LUM – lumbar abdominal nerve, RLN – recurrent laryngeal nerve, and MYP – hypoglossal nerve.
