Figure 4.
(A) Grand average plot of the phase-locking factor (PLF) on Nogo trials at electrode FCz. Warm colors indicate high phase-locking, cold colors denotes low phase-locking. The scatterplots show the correlation between striatal GABA levels and the PLF in the Nogo-N2 time window and the Nogo-P3 time window. Black lines linking the scatter plot with the relative time point (region in the PL-plot) indicate the time point from which the PL for the N2 and the P3 component was extracted. Warm colours in the maps denote electrode sites where the phase-locking factor was high, cold colour denote electrode sites where the phase-locking factor was low. (B) Time frequency plot denoting the total (induced) wavelet power at electrode FCz for Go trials. (C) Time frequency plot denoting the total (induced) wavelet power at electrode FCz for Nogo trials.
