Results: Even though both P3 and 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.
