TFR results during preparation interval. A. Grand average power of neural oscillations in the EEG plotted as a function of oscillation frequency and time after the onset of the incentive array (and before the search array appeared) for low- and high-incentive trials at PO4. B. Grand average of the difference TFRs of power (high- minus low-incentive trials) at PO4. C. Grand average % change in power at 10–14 Hz for low- and high-incentive trials at PO4. D. Grand average topography of the difference TFRs of power (high minus low-incentive trials) averaged over 10–14 Hz and 400–880 ms.
