Abstract
TELEOSTS possess both neural and humoral pigmentomotor control. The neural control of teleost melanophores is known to be autonomic1. A melanophore-aggregating centre exists in the medulla of the minnow (Phoxinus phoxinus L.). A spinal pigmentomotor tract passes caudally from the medulla and has a spinal outflow localized around vertebra 15. The pigmentomotor nerves then pass cephalically and caudally along the sympathetic chains and innervate the melanophores through the spinal and trigeminal nerves2. The investigation recorded here was concerned with the location of the spinal pigmentomotor tract.
