Summary

  1. 1.

    All investigated mesencephalic structures have definite synaptic influences on spinal α-motoneurons. The red nucleus facilitates flexor and inhibits extensor motoneurons. The substantia nigra acts in the same way as the red nucleus on motoneurons, but with less marked reciprocity. The reticular formation and nucleus of Cajal excite all of the flexor and half of the extensor motoneurons. The tectum has a predominantly facilitatory influence on both flexor and extensor motoneurons.

     
  2. 2.

    Experiments with prior destruction of the red nucleus suggest that effects of the reticular formation and substantia nigra on spinal motoneurons may be transmitted through the red nucleus.

     
  3. 3.

    Comparison of the character of influences from the tectum, reticular formation, red nucleus, nucleus of Cajal and substantia nigra suggests that during evolutionary development of the motor system of the mesencephalon an increase in specialization of the individual structures takes place. This is manifested, in particular, by the appearance of reciprocal effects on flexor and extensor motoneurons.
