How to select epochs of cognitive event-related potentials for brain mapping?
Event-related potentials were recorded in healthy volunteers while they were performing cognitive tasks. The new parameter developed for evaluation of how ERPs from different electrodes are not like each other allowed to study the mental chronometry as well as the localization of specific cortical areas. Occipital lobes were most active in passive visual word perception, the left anterior frontal lobe was activated in semantic association. The developed approach allows the combination of imaging and chronometric studies.
