1933 Proc. Soc. Exper. Biol. & Med. 1932–3 30 556 That this stripe should be dark is due to the fact that the severance of the nerve fibers excites the discharge of an expanding neurohumor whereby the melanophores are made to enlarge and thus to darken the skin.

1956 Proc. Royal Soc. B. 145 160 These results revive the hope that a connexion between neurohumour production and the lipotropic factors can be established.

1959 J. H. Welsh in A. Gorbman Compar. Endocrinol. 123 Although it is convenient to refer to the products of ordinary neurons as neurohumors and to those of neurosecretory cells as neurosecretory substances, their common role as regulatory agents must be recognized.

1971 Compar. Biochem. & Physiol. 38 A.239 The neurohumor, serotonin, has been shown to be functionally involved in hibernation in the ground squirrel.

1986 A. S. Romer & T. S. Parsons Vertebr. Body (ed. 6) xvii. 613 The cells of the adrenal medulla do not look like nerve cells, because they lack fibers. But since they are homologous with postganglionic sympathetic neurons, it is not surprising that they produce comparable neurohumors.
