Power spectrum analysis of the BTC model output \(V_{t}\) in frequency domain with decreasing of inhibitory synapse connectivity parameters \(C_{idi}\) from PNN to IN and \(C_{ndi}\) from PNN to TRN. Dependence of the dominant frequency of the model output on \(C_{idi}\) (a) and \(C_{ndi}\) (b). The individual plots of power spectrum density when \(C_{idi}\) (c) and \(C_{ndi}\) (d) take different values. The evolution of relative power in alpha and theta frequency bands during the reduction of \(C_{idi}\) (e) and \(C_{ndi}\) (f).
