Dynamics Analysis of a Time-Delay Neural Mass Model

摘要：

　　In view of signal transmission among neurons being hindered because of nervous system diseases,we propose a modified neural mass model with time delay.The new timedelay model can simulate several different types of EEG activities including ictal EEG.Through the simulation and analysis of influence of the time delay on dynamic behavior of the model,we successfully demonstrate that the time delay of neuronal signal transmission could cause seizure-like activity.We give a preliminary description of the model’s behavior with bifurcation diagrams.Study on bifurcations of this neural mass model could provide further theoretical reference for understanding the neurodynamics of epileptic seizures.
