Background: A subset of normotensive Sprague-Dawley rats show lower baroreflex sensitivity; however, no previous study investigated whether there are differences in baroreflex sensitivity within this subset. Thus, we compared baroreflex among adult spontaneously hypertensive rats (SHR).The authors discuss one type of general forward-backward stochastic differential equations (FBSDEs) with It's stochastic delayed equations as the forward equations and anticipated backward stochastic differential equations as the backward equations. The existence and uniqueness results of the general FBSDEs are obtained. In the framework of the general FBSDEs in this paper, the explicit form of the optimal control for linearquadratic stochastic optimal control problem with delay and the Nash equilibrium point for nonzero sum differential games problem with delay are obtained.Results: Approximately 1/10 of rats presented increased bradycardic baroreflex while around 1/5 showed attenuated tachycardic baroreflex. Rats with higher bradycardic baroreflex presented higher basal HR.Conclusion: There is significant alteration regarding baroreflex sensitivity among SHR from the same laboratory.
