abstract = {Attention is a complex construct that comprises at least
three major subcomponents: alerting, spatial (re-)orienting,
and executive functions, all of which have specific neural
correlates along frontoparietal networks. Attention deficits
are a common consequence of brain damage. Transcranial
direct current stimulation (tDCS) has been shown to modulate
spatial attention. We investigated whether tDCS of different
stimulation targets differentially modulates alerting,
spatial (re-)orienting, and executive functions. Twenty-four
healthy participants were included in this randomized,
double-blinded study, which employed a within-subject
design. On four different days, the effects of 1.5 mA anodal
tDCS (real and sham) on the left dorsolateral (EEG 10–20
point F3), left parietal (P3) and right parietal cortex (P4)
were assessed using a modified attention network test. tDCS
of the right parietal cortex enhanced spatial re-orienting,
while tDCS of the other cortical targets did not modulate
the assessed attention functions. With regard to visual
field asymmetries in attentional processing, right parietal
tDCS selectively enhanced mean network efficiency for
targets presented in the contralateral left visual field.
The observed visual field specific tDCS effects on
reorienting suggest that systematic investigations into
novel approaches for the treatment of patients suffering
from spatial neglect patients are warranted.},
