The arterial baroreflex system may be divided into the neural arc (from pressure input to efferent sympathetic nerve activity) and the peripheral arc (from sympathetic nerve activity to arterial pressure). In rabbits, the baroreflex neural arc reveals derivative characteristics in the frequency range below 0.8 Hz and high-cut characteristics above 0.8 Hz. To examine such high-cut characteristics are also present in rats, we isolated the carotid sinus regions and imposed a Gaussian white noise with a switching interval of 50 ms. The baroreflex neural arc showed derivative characteristics in the frequency range from 0.1 to 1.3 Hz and high-cut characteristics above 1.3 Hz in rats (Figure).
