Information dynamics of in silico EEG Brain Waves: Insights into oscillations and functions
Fig 8
Relation between β rhythms and information transfer in inhibitory neuron population.
The figure only illustrate regions where β rhythms dominate. (A, B) Color maps show clear regions of maximum of PSD for β rhythms in Phase II.a, for both excitatory (A) and inhibitory (B) neuron populations. White regions correspond to other phases (without dominant β waves) that were ignored. Panel (C) shows the maximum transfer of information (see colorbar code on the right of panel D) between partitions of inhibitory neurons within the Phase II.a. Panel (D) illustrates the transfer of information of the bipartition that maximize information transfer in the inhibitory group. Maximum information transfer increases with increasing power of β waves in both neuron populations (region indicated by black arrow), showing that in our system, β waves are related with information transfer between inter-neurons. Panels (A, C, D) depict, however, that there are points where we see a high PSD in β, mainly in the excitatory population (red arrow), that does not relate with an increase in transfer information. Dotted black horizontal line indicates the value of τrec and range of μ used in Fig 9.
