Neurones were classified as expiratory (E) or inspiratory (I), and augmenting (Aug), decrementing (Dec), Other, plateau (Plat), or recruited (Recruit). n, number of neurones (numerator is the number of neurones with primary features in the spike-triggered average; denominator is the total number of neurones used as trigger neurones); OBFmot, offset biphasic feature in unrectified average indicating that the neurone was a motoneurone; CP, central peak; OP, offset peak; OT, offset trough; Direction of change in peakfiring rate during cough: ↑, increase; ↓, decrease; →, no change. The medullary domains in whichrecordings were made are fully defined in the text.
