title: [Laminar distribution of sources of ascending spinocerebral fiber systems in the spinal cord of cats].
abstract: Cells of origin of the spinobular, spinomesencephalic and spinothalamic tracts in the cat brain were identified by the retrograde horseradish peroxidase transport technique. A conclusion is made that neurons in laminae IV and V give rise to ascending fibres to the ipsilateral dorsal column nuclei and neurons in the lateral parts of laminae V and VI and in lamina VIII establish direct connections with the contralateral thalamus (CM, MD, CL) and reticular formation of the brain stem. Throughout the spinal cord the labelled neurons were present in the intermediate zone of both sides.
