title: [Control of voluntary movements mediated via propriospinal neurons].
abstract: Cortico- and rubrospinal tracts play an important role in controlling voluntary movements. Transection of these tracts in different spinal cord layers gives different effects that may be explained by the influence of different spinal cord neuronal networks. The aim of the present work was to study the role of C3/C4 propriospinal system in movement control and processes of motor recovery. It was shown that propriospinal system C3/C4 play crucial role in motor recovery after lesion of cortico- and rubrospinal tracts in C5, whereas ventrally located tracts are important after the same lesion in C2. More over, propriospinal system C3/C4 can mediate the command for some voluntary movements in cats.
