A dynamical systems approach for estimating phase interactions between rhythms of different frequencies from experimental data
Fig 3
Estimated coupling function for numerical simulation data.
Upper-left diagram shows the network structure. The estimated coupling functions (red lines) were nearly identical to the correct functions (dashed black line). The gray dots represent the phase time-series data. When the interaction did not exist, the estimated coupling function was identically zero. The proposed method estimated all coupling functions correctly for the simulation data.
