Název v původním jazyce

Intracerebrally recorded ERPs in a frequency range of 5.5-15 Hz in visual oddball paradigm

Popis výsledku v původním jazyce

In humans alpha responses (8-15Hz oscillations) to sensory stimuli returning to baseline 200-300 ms after stimulus were described. The aim of the present study was to investigate the intracerebral distribution of ERPs in a frequency range of 5.5-15 Hz inhumans. In 7 patients a total of 268 sites were investigated. Visual oddball paradigm was performed. For each subject, approximately 50 trials to target and 100 trials to frequent stimuli were averaged. The sites with prominent ERPs were investigated. In 98 contacts (6 patients) where the prominent ERPs were identified they were present always after both target and frequent stimuli, and they were identical in several successive components (range from 1 to 5) with the peak latency range from 45 to 339 ms. They were found in various brain structures. Simultaneous occurrence of identical components after target and frequent stimuli in different brain structures probably reflects the basic level of processing visual stimuli.
