[Afferent connections of the mesencephalic locomotor area of the cat brain].
Afferent projections to the functionally identified mesencephalic locomotor region were studied in cat by means of the horse-radish peroxidase technique. Quantitative calculation of HRP-labelled neurons in the different brain structures after enzyme injections into mesencephalic locomotor region was made. Apart from the entopeduncular nucleus, different hypothalamic areas and substantia nigra, labelled neurons were found in ventral tegmental area, substantia grisea centralis, raphe and vestibular nuclei, nucleus of tractus solitarius and brainstem reticular formation. Neurons accumulating horse-radish peroxidase were found also in the brainstem sensory nuclei. This fact emphasized the structural heterogeneity of the mesencephalic locomotor region which includes neurons and passing fibers; both of them may be significant during locomotion elicited by the midbrain stimulation.
