title: [Cortico- and rubrofugal influences on interneurons of the superior cervical segments of the cat spinal cord].
abstract: Stimulation of the medullary pyramids and contra- and ipsilateral red nuclei produced short latent EPSPs in interneurons of the lateral part of Rexed's laminae V--VII of the C1--C3 segments of the cat spinal cord. Stimulation of the first and second cervical dorsal roots was not effective in exciting of these neurons. It is supposed that these interneurons represent a relatively specialized group which form, apparently, disynaptic cortico- and/or rubro-motoneuronal pathways.
