摘要

Objective: Following external stimulation, electroencephalographic (EEG) responses from different frequency bands occur simultaneously, but little is known about whether and how concurrent multi-frequency responses depend on each other during stimulus information processing. The present study assessed the effects of task stimulus relevance on locally co-existent time–frequency components of event-related brain potentials (ERPs).
