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.
摘要
刺激延髓锥体以及对侧和同侧红核，在猫脊髓C1 - C3节段Rexed板层V - VII外侧部分的中间神经元中产生了潜伏期短的兴奋性突触后电位（EPSP）。刺激颈1和颈2背根对这些神经元的兴奋无效。据推测，这些中间神经元代表了一个相对特殊的群体，显然形成了双突触皮质和/或红核 - 运动神经元通路。
