Definition:	The terminal nerve, located anterior to cranial nerve I, is comprised of a group of cells with somata adjacent to the olfactory bulb and processes that extend anteriorly to the olfactory epithelium and posteriorly to the telencephalon. In teleost fish an additional group of axons extends along the optic tract and delivers putative neuromodulators to the retina. It is thought to develop from cranial neural crest.
