Article Snippet: Only two studies have analyzed the N170 event‐related potential in Parkinson's disease and no differences in N170 amplitude and peak delay relative to healthy subjects were found (Wieser et al., 2012 ; Yoshimura et al., 2005 ).

Figure Lengend Snippet: The occipital N170 in the emotional condition. (A) Mean event‐related potential amplitude in the occipito‐temporal region in healthy subjects (from the 15 electrodes for each subject with the highest amplitude in the time interval [100–240] ms). The shaded area represents the SEM (across subjects). (B) Topography of the N170 averaged over the time interval [140–200] ms; (C) comparison of the difference in N170 amplitude between the incongruent and congruent trials (i.e., the electrophysiological representation of the magnitude of the Stroop effect): (a) for the OFF DBS (in red) and ON DBS states (in blue); (b) for the OFF levodopa (in blue) and ON levodopa states (in red); (c) for the ON levodopa (in red) and ON DBS states (in blue). As shown in C(a) and C(b) the amplitude of the difference in the peaks of the N170 in the two conditions of congruency is significantly modulated by levodopa but not by DBS [Color figure can be viewed at http://wileyonlinelibrary.com]
