    P3 and ERD/ERS in a Visual Oddball Paradigm

  • Original language description

    The present study investigates intracerebrally the concurrent occurrence of event-related potentials (ERPs) and event-related desynchronization/synchronization phenomena (ERD/ERS) in subjects performing a visual oddball task. Results: Even though both P3and ERD/ERS phenomena were observed in all investigated mesiotemporal regions, the most consistent findings were revealed in the hippocampus. A P3 component of ERP was repeatedly observed in the hippocampus after target stimuli. Significant changes of the oscillatory hippocampal activity were found: ERD in the alpha 1 and alpha 2 frequency bands. Evident, near-significant, changes were observed throughout hippocampus in the theta band. In response to the non-target stimuli, significant oscillatory changes were found in parahippocampal gyrus. Conclusions: The cognitive processing of visual information is simultaneously accompanied by several electrophysiological phenomena.
