| Abstract: | 1. The composition of amino acids, biogenic amines and related enzymes in the brain and other regions of the nervous system was analyzed for the solpugids, Eremobates palpisetulosus and Eremorhax magnus. The most abundant amino acids were Glu, Asp, Pro, Ala and Gly.2. GABA, dopamine, noradrenaline, acetylcholine and acetylcholinesterase were present in the brain. AChE activity was highest in the protocerebrum and cheliceral nerves; no activity was found in the optic or genital nerves.3. Concentrations of amines and ACh were found to increase in the brain during postembryonic development. |
