title: Cardiovascular responses of the bullfrog (Rana catesbeiana) to thermal stimulation of the spinal cord.
abstract: Selective thermal stimulation of the spinal cord was performed in the bullfrog (Rana catesbeiana). Spinal cord warming caused an increase in systolic pressure of the truncus arteriosus, and cooling caused a decrease. Spinal cord warming caused an increase in systolic and pulse pressures of the conus arteriosus, and cooling caused a decrease. These results showed the temperature perceptibility of the spinal cord and a relationship between spinal cord temperature and autonomic functions in the frog as in other endothermic and ectothermic species.
