LOCALIZATION OF WORD AND FACE RECOGNITION MEMORY USING TOPOGRAPHICAL EEG

The aim of this study was to explore the ability of epoch-averaged ele ctroencephalogram (EEG) to localize cognitive functions. The EEG was r ecorded in healthy individuals performing a task where, on the basis o f evidence from other functional brain imaging techniques, there was a high expectation of where functional changes would be expected. Topog raphical EEG was recorded while individuals performed recognition memo ry tasks for words and faces. Comparison of the acquisition and recogn ition phases of the experiment showed significant attenuation of alpha , beta1, and beta2 in the right temporoparietal region for the faces b ut no significant changes for words. Left temporoparietal changes for the word task were only seen among the women. The results confirmed th e validity of EEG for use in the localization of cognitive function fo r faces for men and women but in the case of words for the women only.
