Subject specific EEG patterns during motor imaginary [sic.: for imaginary read imagery]

Abstract

Left- and right-hand movement imagery is accompanied by an EEG event-related desynchronization (ERD) over the contralateral hand area. The time courses of the ERD from two brain-computer interface experiments were investigated by the calculation of instantaneous band power changes and by adaptive autoregressive model parameters combined with linear discriminant analysis. Subject-specific differences of the EEG reactivity patterns were observed.
