摘要: Event-Related Desynchronization (ERD) and Synchronization (ERS) of several EEG alpha frequencies was studied in 19 subjects during the presentation linguistic and/or melodic auditory stimuli. The stimulus length 1300 msec (+/−100 msec) interstimulus interval 2000 msec. A significant ERD found stimulation 8–10 Hz 10–12 frequency bands, there were also differences spatiotemporal pattern between these bands. Significant elicited 10–11 11–12 bands by stimulation. There no one-hertz assigned to two analysis groups according their individual peak (10–11 or Hz) at rest. reached statistical significance groups. differed significantly when data band. results from this study show that is not modality-specific, i.e., it can be Moreover, they indicate important control over interindividual variation studying phenomenon.
