MORPHOMETRIC PROPERTIES OF DORSAL CLARKE’S NUCLEI IN ROSTRAL SEGMENTS OF LUMBAR PORTION OF SPINAL CORD IN CAT

Abstract

Morphometric properties of Clarke’s nuclei and their distribution in gray matter of the cat’s spinal cord were investigated using the methods of histochemical acetylcholinesterase demonstration, immunolabelling of non-phosphorylated domains of heavy neurofilament chains (SMI-32) and Klüver-Barrera technique for myelinated fiber demonstration. As a result of this research, averaged metric maps for LI-LIV lumbar segments of the spinal cord with Clarke’s nuclei boundaries were constructed based on the data received on 5 cats. The work provides information essential for precise stereotaxic access to Clarke’s nuclei in future fundamental and applied studies.
