Information dynamics of in silico EEG Brain Waves: Insights into oscillations and functions
Fig 14
Emergence of γfast rhythms in I groups and information dynamics.
Colors indicate the level of maximum power density in the γfast band. The data points in (A) correspond to points of high activity ρI of the inhibitory population (region II.b) as shown in the inset (C) of the figure. The scatter plot of differentiated (
) and redundant (
) information in inhibitory groups, respectively, shows that the points of highest intensity of inhibitory fast γ oscillations have the lowest 
and 
observed in the data. These points are those where excitatory and inhibitory oscillations coexist (see Fig 13F). (B) By grouping data in power spectrum density (PSD) intervals and computing the mean and standard deviation of time-delayed mutual information (TDMI), we observe a clear inverse relation between inhibitory oscillations amplitude and mutual information. The black dashed lines in (B) are the averaged TDMI of all data.
