FUNCTIONAL HEMISPHERIC AROUSAL AND EGOCEN TRIC REFERENCE - AN EXPERIMENTAL-STUDY ON 20 HEALTHY-SUBJECTS

The aim of this study was to evaluate the influence of each hemispheri c functional arousal (right or left) on the designation of a subjectiv e egocentric reference. The subjective designation of a egocentric ref erence was measured and compared in 20 right-handers healthy volunteer s in cognitive tasks concerning either the right or the left hemispher e. The location of the egocentric reference was different during right or left hemispheric arousal. The hemispheric arousal induce a displac ement of the egocentric reference to the contralateral space. These re sults are compared with clinical and neurophysiological studies and su ggest new explorations to the mechanisms of heminegligence.
