“…All studies were sham controlled, except Turgut et al (2016) and Bang and Bong (2015) A anodal, C cathodal, ref location of tDCS electrode that was not of interest, Online task performed during stimulation, Offline task performed after stimulation, Dosage zero-to-peak amplitude Presumably, tDCS increased the activity of the left parietal cortex beyond that of the right, causing a rightward shift in spatial bias. Similarly, Giglia et al (2011) report a rightward shift for right cathodal tDCS (although note that Loftus and Nicholls (2012) did not find this). They furthermore observed that a Bdual^montage with one electrode on each posterior parietal cortex (anode left; cathode right) was even more effective.…”

Attention is a fundamental cognitive process-without it, we would be helplessly adrift in an overload of sensory input. There is considerable interest in techniques that can be used to enhance attention, including transcranial electrical stimulation (tES). We present an overview of 52 studies that have paired attention tasks with tES, mostly in the form of transcranial direct current stimulation (tDCS). In particular, we discuss four aspects of attention that have been most extensively targeted to date: visual search, spatial orienting (e.g., Posner cueing tasks), spatial bias (e.g., line bisection tasks), and sustained attention. Some promising results have been reported in each of these domains. However, drawing general conclusions about the efficacy of tES is at present hampered by a large diversity in study design and inconsistent findings. We highlight some pitfalls and opportunities and suggest how these may be addressed in future research aiming to use tES as a tool to enhance or test theoretical hypotheses about attention.

“…More recently, Giglia et al [15] used dual tDCS stimulation over the same areas to induce neglect-like effects in healthy subjects. Also fMRI studies supported the activation of the right parietal lobe in healthy humans during line-bisection tasks in the near space [16e18].…”

“…Within this context, Giglia et al (2011) investigated in healthy subjects whether tDCS may induce neglect-like symptoms outlasting stimulation. Neglect-like symptoms were assessed in 11 subjects when performing judgements on prebisected lines (i.e., the Landmark task).…”

“…Neglect-like symptoms were assessed in 11 subjects when performing judgements on prebisected lines (i.e., the Landmark task). Furthermore, Giglia et al (2011) investigated whether bilateral stimulation (at 1 mA for 15 min, pair of approx.. 4 Â 4 cm 2 electrodes) of right (P6) versus left parietal cortices (P5) compared with unilateral right cathodal stimulation (with the reference electrode at the left orbita) caused greater or longerlasting effects. Both stimulation conditions, dual/bilateral as well as unilateral right PPC cathodal stimulation, induced a rightward bias in symmetry judgements compared with baseline and sham stimulation.…”
