Trigeminocerebellar Projection in the Carp (Cyprinus carpio)

Abstract:

Tract-tracing methods were used in our research to observe the fibrae connection between cyprinoid nucleus sensorius nervi trigemini and cyprinoid cerebellum. After biotinylated dextran amine (BDA) was injected into cyprinoid principal nucleus sensorius nervi trigemini, the direct motioned extremity sensorius nervi fibers of trigeminal nerves was observed exist in hibateral cerebellum nucleus lateralis valvulae, principally distributed in the contralateral hibateral cerebellum nucleus lateralis valvulae. No extremity sensorius nervi fibers of trigeminal nerves was marked. If BDA was injected into regressed motioned extremity sensorius nervi fibers of trigeminal nerves of cyprinoid hibateral principal nucleus sensorius nervi trigemini and trigeminal nerves descended nucleus, most of them were observed in opposite side. The direct motioned marked extremity sensorius nervi fibers were observed in cerebellum and valvula cerebelli. Most of the cerebellum label neurons injected by BDA existed in tautomeral nucleus lateralis valvulae, only a few of them were in opposite side. The results of our research proved that centrifugal fibers of cyprinoid nucleus sensorius nervi trigemini project indirectly onto cerebellum through nucleus lateralis valvulae .
