AI Article Synopsis
- The study explored how activating either the right or left hemisphere of the brain affects how individuals perceive their own body in space.
- Researchers tested 20 healthy right-handed participants and found that the location of their egocentric reference shifted based on which hemisphere was stimulated.
- These findings align with existing clinical studies and could lead to further investigation into the underlying mechanisms of heminegligence, where patients neglect one side of their body.
Article Abstract
The aim of this study was to evaluate the influence of each hemispheric functional arousal (right or left) on the designation of a subjective egocentric reference. The subjective designation of a egocentric reference was measured and compared in 20 right-handers healthy volunteers in cognitive tasks concerning either the right or the left hemisphere. The location of the egocentric reference was different during right or left hemispheric arousal. The hemispheric arousal induce a displacement of the egocentric reference to the contralateral space. These results are compared with clinical and neurophysiological studies and suggest new explorations to the mechanisms of heminegligence.
