Undiminished reflex responses of adrenal sympathetic nerve activity to stimulation of baroreceptors and cutaneous mechanoreceptors in aged rats.
Reflex responses of adrenal sympathetic nerve activity to stimulation of baroreceptor and cutaneous mechanoreceptors were compared in young adult (4 months old) and aged (26 months old) rats, under strictly controlled conditions for anesthesia, respiration and body temperature. Under these conditions the reflex depression to baroreceptor stimulation and cutaneous brushing and reflex excitation to cutaneous pinching were quite well maintained during aging.
