Examples of V1 LFP power spectral density (PSD) changes triggered by BF stim. The gray and black traces represent the PSD ± SEM before and after BF stimulation respectively. The different panels represent examples for the different observed patterns: (a) 40Hz γ-band peak (b) 70Hz γ-band peak (c) Both 40Hz and 70Hz γ-band peaks (d) Decrease in the low frequency (0–10Hz) band and broad increase in the γ-band. (e) Increase in both low and high frequency band, no peaks.
