Abstract

<p>The authors have measured electroencephalograms (EEGs) from subjects observing images of part of fruit and recalling them silently. The equivalent current dipole source localization (ECDL) method has been applied to those event related potentials (ERPs): averaged EEGs. ECDs were localized to the primary visual area V1 around 100msec, to the ventral pathway (TE) around 270msec, to the parahippocampal gyrus (paraHip) around 380msec. Then ECDs were localized to the Broca’s area around 450msec, to the fusiform gyrus (FuG) around 600msec, and again to the Broca’s area around 760msec. Process of search and preservation in the memory has been done from the result of some ECDs to the paraHip. With or without activities on the angular gyrus (AnG) are important to discriminate of the presented images.</p>
