Abstract:
The origins of the afferent fibers of the parafascicular nucleus were studied with the retrograde tracing method of HRP in eight rats by injecting HRP into the left thalamic parafascicular nucleus. The labeled cells were found mainly in the bilateral reticular formation, the ipsilateral central gray, intermediate and deep gray layers of the superior celliculus and some area of the cerebral cortex. A few labeled cells were found in the contralateral dorsal horn of spinal cord. The labeled cells were also found to varying degrees in some other nuclei of the brain.The modified injection method of concentric glass-micropipettes was discussed.The origins of afferent fibers of parafascicular nucleus and their functions concerned with pain were discussed.
