Neural
Definition:
(a.) relating to the nerves or nervous system; taining to, situated in the region of, or on the side with, the neural, or cerebro-spinal, axis; -- opposed to hemal. As applied to vertebrates, neural is the same as dorsal; as applied to invertebrates it is usually the same as ventral. Cf. Hemal.
