Type indicates whether the baroreflex was active when pressure was increased (hypertensive) or when pressure was increased and decreased(complete). G50, maximal baroreflex gain; G50,norm, normalized maximal baroreflex gain; resting a, resting mean arterial pressure; aG50, mean arterial pressure at G50. aG50 could not be calculated in embryos because the data were not ditted to a sigmoidal baroreflex model. See Materials and methods for further details.
