Özet

Purpose: The typical novelty paradigm in cognitive electrophysiology is rin experimental design, in which the ejects of novel stimuli on brain electrical activity are measured using unexpected and ever-changing novel non target stimuli interspersed in the set carstandards rind targets (tithe classical oddball paradigm. The typical event-related potential (ER?) component obtained during the novelty paradigm is a N2-P3a complex occurring in response to tinveltinn-targets. The aim nf present study is to determine more specific ER? component jOr detection oftinvelty
