Termination and cells of origin of the ascending intra-nuclear fibers in the spinal trigeminal nucleus of the cat. A study with the horseradish peroxidase technique.
Termination and cells of origin of the ascending intranuclear fibers in the spinal trigeminal nucleus were studied with the anterograde and retrograde horseradish peroxidase (HRP) techniques in the cat. HRP injections into the nucleus caudalis labeled many axons ascending ipsilaterally within the trigeminal spinal nucleus. These fibers gave off collaterals to the nucleus interpolaris and oralis, and the ventral part of the principal sensory nucleus. HRP injections into the principal sensory nucleus labeled ipsilaterally many small neurons in the caudal portion of the nucleus interpolaris and in laminae III and IV of the nucleus caudalis. A few neurons were labeled in laminae I and V.
