A) Extracellular electrodes were placed on the surface of the VRG to record population activity. Intracellular electrodes were placed close to the extracellular electrodes to simultaneously record inspiratory neuron activity. B) Raw VRG population activity was integrated (ʃ); the integrated VRG activity is dominated by inspiratory neurons, giving rise to fictive inspiratory bursts in the integrated traces (ʃVRG). Lower trace is a simultaneous intracellular recording of inspiratory neuron bursting in phase with the population.
