[Efferent projections of neurons of the mesencephalic locomotor region of the cat brain].

Efferent projections of mesencephalic locomotor region neurons were studied by means of horseradish peroxidase technique in cat. Ascending and descending projections of these neurons to different structures of the brain with predominant course to the brainstem reticular formation were traced. Some fibres passed through the bulbar and spinal locomotor strip. Mutual bilateral interconnections of the mesencephalic locomotor regions were observed.
