In the present study, we combined tDCS and EEG to examine the
electrophysiological responses to the tDCS-induced effects on
the face inversion effect showed in recent studies. A double-blind
procedure with a between-subjects design (n=48) was used with
the subjects, recruited from the student population, being
randomly assigned to either tDCS anodal or sham condition. The
tDCS stimulation was delivered over the DLPFC at Fp3 site for
10 min at an intensity of 1.5mA while subjects engaged in an
old/new recognition task traditionally used to obtain the
inversion effect. The behavioural results generally confirmed
previous findings. Critically, the results from the N170 show an
effect of tDCS. Specifically, the tDCS procedure was able to
modulate the N170 peak component by reducing the inversion
effect on the latencies (i.e. less delay between upright and
inverted faces) and by increasing the inversion effect on the
amplitudes (i.e. larger N170 for inverted vs upright faces). We
interpret the results based on the previous literature in regard to
the inversion effect on the N170 component.
