This
article reviews data on changes in indicators obtained from
multichannel EEG, MRI, fMRI, and diffusion tensor tractography in
poststroke patients during motor recovery. The main indicators most
commonly analyzed in the literature on changes in the brain occurring
both during traditional motor rehabilitation and during rehabilitation
procedures using brain–computer interface technology are considered.
Changes in the indicators discussed here reflect the dynamics of the
involvement of the hemispheres, individual areas of the brain, and
connections between them in solving motor tasks and constitute a
manifestation of both instant functional rearrangements of the network
and genuine neuroplastic (structural) changes in the brain. The
functional roles of the hemispheres, individual areas, and connections
between areas in the process of motor rehabilitation after stroke are
discussed.
