part of start stage end stage midbrain rhombencephalic octavolateral efferent neuron ROLE neuron zebrafish_anatomy Efferent neuron located in the hindbrain. The axon of ROLE cells travels rostrally near the ipsilateral medial longitudinal fascicle to the level of the Mauthner cell where it turns laterally to exit with the eighth nerve. Outside the brain the axon continues ventrally to the base of the saccular macula in the ear then turns caudally to ender the ganglion of the posterior lateral line. A branch of the axon turns ventrally before the main axon enters the LLG. The branch goes ventrally along the wall of the otic capsule.
