From: The Bogdanov-Takens bifurcation study of 2m coupled neurons system with \(2m+1\) delays
Pitchfork bifurcation is shown with initial values \(\pmb{(u_{1}(0),u_{2}(0),u_{3}(0),u_{4}(0))=(0.00053, 0.004, 0.0002, 0.0004)}\) (green curve), \(\pmb{(-0.00053, -0.004, -0.0002, -0.0004)}\) (blue curve), \(\pmb{(0.5, 0.4, 0.3, 0.4)}\) (red curve). (a) The time series when \((\alpha_{1},\alpha_{2})=(-0.001, -0.001)\). (b) The time series when \((\alpha_{1},\alpha_{2})=(-0.001, -0.006)\).
