From: Open-loop static and dynamic characteristics of the arterial baroreflex system in rabbits and rats
Example of static characteristics of the total reflex arc from carotid sinus pressure (CSP) to arterial pressure (AP) obtained in Sprague–Dawley rats. a Quantification using a four-parameter logistic function. b Gain curve obtained from the first derivative of the fitted logistic function. c Quantification using an integral of a bell-shaped gain curve function. d Bell-shaped gain curve function corresponding to panel c. P 1 response range, P 2 slope coefficient, P 3 midpoint input pressure, P 4 minimum response. G max maximum gain, σ standard deviation, μ midpoint input pressure, y 0 minimum response. In panels a and c, data points represent mean ± SE values (n = 12)
