title: Cells of origin of propriospinal and ascending supraspinal fibers in a lizard (Lacerta galloti).
abstract: The location of cells of origin of propriospinal and ascending supraspinal fibers has been determined by injecting horseradish peroxidase (HRP) unilaterally into various parts of the spinal cord of the lizard Lacerta galloti. The distribution of retrogradely labeled cells after unilateral high spinal cord injections suggests that ascending supraspinal fibers are derived from neurons in the following areas: in the cervical intumescence in most areas of the spinal gray, particularly ipsilaterally, in thoracic and lumbar segments, in deeper situated areas, especially contralaterally. The presence of cells of origin of long descending propriospinal pathways has been demonstrated following HRP-injections into the lumbar intumescence.
