Key result
Rat aortic baroreflex responses to electrical stimulation are sustained even at very high input frequencies (>100 Hz), presenting a paradox for central integration understanding.

Anesthetic choice alters baroreflex frequency responses in rats; leaves open translation to conscious animals or clinical settings.
Fan et al. (1996) studied this question. Electrical stimulation of aortic depressor and carotid sinus nerves vs. Different anesthetics (pentobarbital sodium vs alpha-chloralose and urethan) was evaluated on Mean arterial pressure and heart rate reflex responses. Rat aortic baroreflex responses to electrical stimulation are sustained even at very high input frequencies (>100 Hz), presenting a paradox for central integration understanding.
