The nervous system of the crayfish contains a peptide of low molecular weight which depresses the spontaneous electrical activity of motoneurons in the abdominal ganglia. Most of this substance is contained in the sinus gland, a neurohemal organ in the eyestalk. Electrical stimulation of the isolated sinus gland, or its incubation in potassium-rich solutions (20--80 mM) results in the release of the neurodepressing peptide. The release is calcium-dependent and appears to involve a process of exocytosis. The released product shows electrophoretic properties undistinguishable from the substance present in the sinus gland.
小龙虾的神经系统含有一种低分子量肽，它能抑制腹神经节中运动神经元的自发电活动。这种物质大部分存在于窦腺中，窦腺是眼柄中的一个神经血器官。对分离出的窦腺进行电刺激，或将其置于富含钾的溶液（20 - 80 mM）中孵育，会导致神经抑制肽的释放。这种释放依赖于钙，且似乎涉及胞吐作用过程。释放出的产物显示出与窦腺中存在的物质无法区分的电泳特性。
