The purpose of the present study was to examine the cardiorespiratory responses (CR) evoked by a somatosympathetic reflex (SSR) in the working heart-brainstem preparation (WHBP). Sprague–Dawley rats (75–100 g) were anesthetized with halothane, bisected sub-diaphramatically and decerebrated pre-colli...
