Study on chaotic characteristics of adrenal axis hormone pulse secretion
This paper mainly studies the chaotic behavior of adrenal axis hormone pulse secretion.Firstly,Matlab software is used to solve the non-uniform oscillation solution and period-doubling oscillation solution of this system,and the phase diagram and bifurcation diagram are drawn.According to the non-uniform oscillation solution,the characteristic quantity of adrenal axis hormone secretion is calculated,and the conclusion is in agreement with the experimental value of hormone characteristic quantity.It is suggested that the pulse secretion of hormone has two possibilities:non-uniform oscillation and chaos.Secondly,by solving the numerical solution of hormone pulse secretion,Matlab software is used to draw the chaotic attractor diagram,bifurcation diagram and Lyapunov index diagram of the system,which proves that the hormone secretion process is chaotic.
