Abstract
The authors measured electroencephalograms (EEGs) from subjects looking at line drawings of body parts and recalling their names silently. The equivalent current dipole source localization (ECDL) method is applied to the event related potentials (ERPs): summed EEGs. ECDs are localized to the primary visual area V1, to the ventral pathway (ITG: Inferior Temporal Gyrus), to the parahippocampal gyrus (ParaHip), the right angular gyrus (AnG), the right supramarginal gyrus (SMG) and the Wernike’s area. Then ECDs are localized to the Broca’s area, the postcentral gyrus (PstCG) and the fusiform gyrus (FuG), and again the Broca’s area. These areas are related to the integrated process of visual recognition of pictures and the recalling of words. Some of these areas are also related to image recognition and word generation. And process of search and preservation in the memory is done from the result of some ECDs to the paraHip.KeywordsElectroencephalogramsbrain activityevent related potentialsequivalent current dipole source localizationword recognition
