Abstract
The paper examines the problem of the primary motor cortex (or M1) determination, which is one of the principal brain areas involved in the motor function. The experiment, based on the method of caused potentials, was conducted to locate M1 area: caused potentials were obtained from the nervous system in response to tactile stimulation of a forefinger. During the experiment, both myogram and magnetoencephalogram (MEG) signals were recorded simultaneously. The associative filter, utilizing moments of the begining of the movement (reference points) of the myogram signal, was applied for processing the MEG signal. This article introduces a new high-precision method for reference points detection.
