[Amplitude modulation of an electroencephalogram, connected with initiation and cessation of movement]

Abstract

Amplitude modulations of electroencephalogram were studied under the condition of single voluntary movements of different duration, their mental reproduction and unvoluntary movements (T-reflex). Specific patterns of the averaging integrated electroencephalogram (waves P1, N1, P2) were detected under initiation or termination of the voluntary movements and their mental reproduction. EEG amplitude modulations were analysed with the accompanying movement of different duration. The experiments showed interferation waves P1, N1, P2 under brief movements. These specific patterns of EEG could be represented by the efferent and afferent components of the central motor programs.
