In other words, the prolonged elevation of [f.sub.H] in intact animals may arise from long-term increases in cardioaccelerator or decreases in cardioinhibitor tonic firing rates.
Our data support the conclusions that the cardioinhibitor nerves are responsible for startle-induced bradycardia and that the cardioaccelerator nerves cause the rapid-onset tachycardia associated with walking.
