FIGURE 13 | Comparison between the dominant oscillatory frequencies in the background, stimulus-phase-independent, and stimulus-phase-locked oscillations. (A–C) Distributions of the dominant frequencies for all types of oscillations found for individual neuronal activity. Inserts represent raster distributions from which histograms were prepared. (D) Pairwise comparison of frequencies found in sSC cell activity showing and background oscillations. (E) Comparison of frequencies found in single neuron activity showing both phase-locked and background oscillations. (F) Comparison of frequencies found in the activity of cells with stimulus-phase-locked and stimulus-phase-independent
