D’ values were significantly and marginally higher for the temporal and parietal groups respectively, compared with the sham stimulation group.

<p>D’ value is zero at random choice. Error bars represent standard error of the mean. Asterisk indicates significant differences; the plus sign indicates marginally significant differences.</p
