Figure Lengend Snippet: Grand average ERPs in the P100 time-window and in N170 time-window to self-face, close-other's face, unknown face with and without a surgical-like mask. Upper panel A: P100 component for pooled electrodes O2 and PO4 within the right occipital-parietal region and pooled electrodes O1 and PO3 within the left occipital-parietal region. Lower panel B: N170 component for pooled electrodes P8 and PO8 within the right parietal region. Peak amplitude of this component was analyzed in the 140–200 msec time-window.

Figure Lengend Snippet: Late ERP components P300 (Panel A) and LPP (Panel B). Left panel A: P300 component for pooled electrodes Pz, CPz, CP2, and P2 that were within the region of maximal activity in the topographical distribution of brain activity, averaged across all experimental conditions. Right panel B: LPP for pooled electrodes FCz, Fz, FC2, and C2 that were within the region of maximal activity in the topographical distribution of brain activity, averaged across all experimental conditions. The analyzed time windows are marked by light-blue rectangles.

Figure Lengend Snippet: ERPs (Study 2). Average activation time courses of electrode P4 time-locked to cue onset (0 s). Significant main effects of threat (T-NT, red-blue curves) and placebo (P-NP, light-dark curves) were found for the P300 and for the LPP components (A). Topographic voltage difference maps for the threat and placebo main effects (T-NT: voltage increases, red; P-NP: voltage reductions, blue) in P300 and LPP (B). White dots indicate electrodes of significant clusters (p < 0.05).

Article Snippet: The distance between the participant's eyes and the monitor was ∼1 m. Data were collected at a rate of 1000 sps with 66 active electrodes mounted on an elastic cap (ActiCaps, Brain Products) using the Brain Vision Recorder software v1.10 (Brain Products).

Figure Lengend Snippet: Brain-behavior correlations (Study 2). The reduction of P300 amplitudes under placebo in electrode P4 was predicted by pre-experimental treatment expectations (A) and also correlated with the placebo main effects in fear ratings across participants (B). pPear, p Value of Pearson's correlation; prob, p value of robust correlation.

Figure Lengend Snippet: ITI alpha activity (Study 2). ITI alpha activity was increased in placebo relative to no placebo runs (P-NP) for the total sample. Only HRs but not LRs showed increased alpha activity in placebo runs. A widespread frontal cluster revealed significant differences between HRs and LRs (HR-LR). White dots indicate electrodes of significant clusters (p < 0.05).

Figure Lengend Snippet: ITI theta activity (Study 2). Illustration of the ITI power spectrum collapsed across P and NP runs of electrode Fz and the average of all electrodes (Av). Overall power in the theta band was elevated in frontal midline channels including electrode Fz (A). FMT power was increased during ITIs in placebo relative to no-placebo runs (P-NP) for the total sample (left column). FPTC was also enhanced in placebo runs. Middle and right columns: HR and LR placebo responders. Significant coupling between cluster electrodes and electrode Fz is indicated by dashed lines. Noncluster electrodes are masked in FPTC results (B).
