Respiratory responses evoked by switching phases

Nicolini Antonello

Phrenic discharge was used as the indicator of the central respiratory cycle, with the inspiratory and expiratory phases, respectively, being specified as the times of phrenic activity and of phrenic silence. The effects of stimulation were labelled operationally as inspiratory-facilitator or expiratory-facilitator on the basis of changes elicited by stimulation during both the inspiratory and expiratory phases. An example of each type of effect, elicited by a relatively long train of high-frequency stimulation.
