Abstract

The neuronal network of the hydrozoan polyp Coryne sp. contains RFamide-positive neurons. Within the body column, these neurons are centralized in a basal ring and a distal field of ganglionic cells surrounding the peristome. The capitate tentacles are traversed by thick RFamide-positive neurites. Their pericarya are centralized in the knobby heads of the tentacles, forming a brightly fluorescing plaque after immunolabeling with an antibody against the RFamide sequence. Numerous dendrite-like extensions project from these cells towards the cell bodies of the nematocytes. The possible role of these dendrites in communication between adjacent nematocytes is discussed.

摘要

水螅虫类珊瑚虫Coryne sp.的神经网络包含RFamide阳性神经元。在体柱内,这些神经元集中在一个基部环和围绕口缘的神经节细胞远端区域。头状触手被粗大的RFamide阳性神经突穿过。它们的胞体集中在触手的瘤状头部,在用针对RFamide序列的抗体进行免疫标记后形成一个明亮荧光的斑块。许多树突状延伸从这些细胞向刺细胞的细胞体伸出。讨论了这些树突在相邻刺细胞之间通讯中的可能作用。
