The recruitment times and firing patterns of the medullary respiratory neurones of the cat.

The brainstem of anaesthetized cats was explored for respiratory neurones with microelectrodes in the regions of the nucleus retroambigualis (ventrolateral region) and the nucleus tractus solitarius (dorsomedial region). These neurones were analysed with respect to their firing patterns and recruitment times, as referenced to the respiratory cycle. All of the respiratory neurones showed a stable and ordered pattern of firing. Four groups of neurones with similar characteristics within each group, but differing from each other, were statistically examined; the inspiratory neurones of the dorsomedial region, the 'late' inspiratory neurones of the ventrolateral region, the 'early' inspiratory neurones of the ventrolateral region and the expiratory neurones of the ventrolateral region.
