Qısa məlumat

The authors have measured electroencephalograms (EEGs) from subjects observing images of 4-legged mammal and/or fruit, and recalling their name silently. The equivalent current dipole source localization (ECDL) method has been applied to the induced event related potentials (ERPs): averaged EEGs. The equivalent current dipoles (ECDs) were localized to the primary visual area V1 around 100ms, to the ventral pathway (TE) around 270ms, to the parahippocampal gyrus (ParaHip) around 380ms. Then ECDs were localized to the Broca's area around 450ms, to the fusiform gyrus (FuG) around 600ms, and again to the Broca's area around 760ms. According to the previous researches, the process of search and preservation in the memory is presumed to be done in the ParaHip. From the results of the present experiment, the authors supposed that both long shape and round shape visual stimuli are processes by Wernicke's area, but only long shape pass through angular gyrus (AnG) before arriving at Wernicke's area.
