Firing patterns of bulbar respiratory neurones during sniffing in the conscious, non-paralyzed rabbit.
On the basis of their firing patterns, 143 of 189 cells recorded in the respiratory centres of conscious, non-paralyzed rabbits could be identified as respiratory related units (RRUs). The activities of 45 RRUs were analyzed during sniffing in response to an odour stimulus. During sniffing as well as during normal breathing neuronal activity and respiratory movements were synchronized. Synchrony was lost, however, at the start of sniffing, indicating an action of the olfactory system on the respiratory generating mechanisms.
