A computer simulation of the system (2.1)–(2.2) with \(a_{1}=0.1450\), \(a_{2}=0.6937\), \(b_{1}=0.0596\), \(b_{2}=0.0206\), \(\alpha _{1}=0.16385\), \(k_{1}=15.64\), \(k_{2}=12.4113\), \(\tau =\tau _{0}=22.5131\), where \(M(0)=5\) and \(G(0)=0.1\), for which all conditions in Theorem 4 are satisfied. The solution trajectory exhibits periodic behavior as theoretically predicted
