The main source of expiratory drive to respiratory muscles in the rat is thought to be the caudal expiratory neurones. However, their projections to the spinal cord and the coordination of the population activity with the respiratory cycle are largely unknown. We examined their bulbospinal projections using antidromic activation, and the coordination of their activity using cross-correlation. Of 76 expiratory neurones examined, 40% projected to the C2 segment of the spinal cord, all… CONTINUE READING
