Modulation of excitatory and inhibitory circuits for visual awareness in the human right parietal cortex.

2005

The balance of specific patterns of excitation and inhibition in critical regions of both hemispheres could be relevant in orienting attention over the extrapersonal space. In the present study a group of normal subjects had to detect small rectangular stimuli presented briefly on a computer screen in three different conditions: unilateral presentation either to left or right visual periphery or bilateral simultaneous presentation. Paired transcranial magnetic stimulation (TMS), was applied over the right parietal cortex 150 ms after the presentation of the visual stimuli with different inter-stimulus intervals (ISIs: 1, 3,5 and 10 ms). When paired TMS was applied 150 ms, but not 100 ms, af…

Can Wii ® remap far into near space?

2018

Background: healthy subjects show in the near space a slight attentional bias toward left (pseudoneglect) that shifts toward right when the task is performed in the far space. This bias moves back again to the left when the subject uses a tool, according to its ability to remap far into near space. On the other hand, when a laser pointer is used to this aim, no significant effects are observed as compared to no-tool condition. This phenomenon has been interpreted as due to the lack of tactile-proprioceptive feedback. Objective: the aim of the present study was to investigate if the use of an interactive tool without tactile- proprioceptive feedback, a three axis accelerometer that works wit…

Reducing Visuospatial Pseudoneglect in Healthy Subjects by Active Video Gaming

2023

Pseudoneglect phenomenon refers to a condition in which healthy subjects tend to perceive the left side of exactly bisected lines as being slightly longer than the right one. However, behavioural data showed that athletes practising an open-skill sport display less pseudoneglect than the general population. Given the fact that so-called exergames (also known as active video games) are platforms designed to fully mimic sport activity, this work intends to investigate whether and how a one-week training period of exergame open-skill sport can determine a similar decrease in pseudoneglect. Fifteen healthy participants (non-athletes) responded to a visuospatial attention task and a control memo…
