We examined the ability of somatic afferent nerve stimulation to entrain inspiratory onset in the anaesthetized spontaneously breathing rat, and compared features of this stimulus–ventilatory coupling to entrainment of inspiratory onset by cardiac activity. In 14 rats prior to stimulation, we common...
