FIGURE 10 | Relation of frequencies found as stimulus-phase-locked, stimulus-phase-independent, and background oscillations for one neuron. (A) raster plot showing stimulus-phase-locked oscillations. (B) PSTH of response showed in (A) , averaged over 100 trials (0.5ms resolution). (C) ACH PSTH prepared from PSTH in (B) revealed stimulus-phase-locked oscillations at 10Hz. (D) cACH after removing the shift predictor, showed the presence of oscillations at a much higher frequency [cf. (C) ]. (E) ACH of background activity after visual stimulation, revealed similar oscillatory frequencies as in panel (C) . (F) Shift predictor for the same neuron indicating the same frequency as in (C) . (G–J) Power spectra for (C–F) ,
