Information dynamics of in silico EEG Brain Waves: Insights into oscillations and functions
Fig 6
Phase diagram of emerging rhythms in the model.
Rhythms observed in the (A) excitatory and (B) inhibitory neuronal population across the phase diagram. Each color shows a specific band of brain rhythms. The regions were defined as areas in the parameter space where the maximum PSD in a given band exceeds 1011, except for γLow where the threshold is 1010. Additionally, for the inhibitory case, the threshold for δ waves is 2 × 1010. In the white regions, maximum PSD values in each band are below the corresponding thresholds, which means there is not a clear dominant rhythm. The colored stars indicate the point of highest maximum power for each rhythm. The detailed PSD for each band is presented in Fig A in S1 Appendix. The solid line indicates a second-order phase transition (absorbing-active phase transition); dashed line indicates a first-order phase transition. Dotted and dash-dotted lines indicate the onset of transition to a LAI phase, for the excitatory and inhibitory population respectively. Vertical and horizontal black arrows indicate the values of μ and τrec for which full spectrum is shown in Figs C and D in S1 Appendix respectively.
