The aim of this study was to explore the ability of epoch‐averaged electroencephalogram (EEG) to localize cognitive functions. The EEG was recorded in healthy individuals performing a task where, on the basis of evidence from other functional brain imaging techniques, there was a high expectation of where functional changes would be expected. Topographical EEG was recorded while individuals performed recognition memory tasks for words and faces. Comparison of the acquisition and recognition phases of the experiment showed significant attenuation of alpha, betal, and beta2 in the right temporoparietal region for the faces but no significant changes for words. Left temporoparietal changes for the word task were only seen among the women. The results confirmed the validity of EEG for use in the localization of cognitive function for faces for men and women but in the case of words for the women only.
