Amplitude Death in Coupled Oscillatory Systems Inspired by Brain Networks with Different Frequency

In this study, we investigate amplitude change and amplitude death in coupled van der Pol oscillators with different oscillation frequency. The network topology is inspired by the concept of a real brain network. We observe the amplitude death of all oscillators when the coupling strength reaches to the certain value. We also confirm that the characteristics of amplitude death depends on the position of oscillator with different oscillation frequency.
