Topic: visuospatial attention

Previous research suggests that electrical stimulation over posterior parietal cortex (PPC) can modulate visual cognition that requires selective attention, yet the specific neural processes affected remain unclear. We hypothesized that tDCS over the PPC influenced the distribution of visuospatial attention by mediating the way selective attention wrap visuocortical processing. We tested this hypothesis using unilateral transcranial direct-current stimulation (tDCS) to the PPC of male and female human volunteers before we recorded electroencephalography (EEG) and collected psychophysical data.

Pseudoneglect phenomenon is a visuospatial attentional bias present in the healthy population, leading subjects to slightly overestimate the left hemifield of space. Interestingly, previous data indicate that athletes involved in open-skill sports exhibit a reduced pseudoneglect compared to the general population. This study aims to explore whether a one-week training period with an open-skill sport exergame can similarly diminish pseudoneglect in healthy subjects. Fifteen non-athletes participants underwent a visuospatial attention task and a control memory task in baseline conditions (t0: Pr
