part of start stage end stage lateral line system diencephalon diencephalic efferent neurons to the lateral line ZFA:0005806 2014-06-24T11:50:49Z Efferent neurons located ventrally in the diencephalon. The dendrites extend into a large area of the diencephalic neuropil rostral, caudal, lateral and ventral to the cell body. The axon courses dorsally and then caudally through the midbrain. As the axon descends through the brain it gives off branches at several levels. One branch usually exits the brain with the posterior lateral line nerve. The axon can be traced into the cervical spinal cord. Ceri There may be 2 neuron types grouped under this name since there are some instances the axons were seen to exit with the eighth cranial nerve instead of the PLL nerve: ZDB-PUB-961014-768. zebrafish_anatomy DELL neuron efferent neuron unknown adult
