Testing the activation-orientation account of spatial attentional asymmetries using transcranial direct current stimulation

► Examined if tDCS over the posterior parietal cortices (PPC) affects pseudoneglect. ► Pseudoneglect was measured before and after anodal, cathodal and sham tDCS. ► Pseudoneglect was significantly reduced by anodal tDCS over the left PPC. ► Pseudoneglect was unaffected by sham and cathodal tDCS of left PPC. ► Pseudoneglect was unaffected by anodal, sham and cathodal tDCS of right PPC. ► Findings support of an activation-orientation model of Pseudoneglect. ► Implications for models of left neglect are considered.
