NEUROBIOLOGY AND BEHAVIOR

Occurrence and Distribution of RFamide-Positive Neurons Within the Polyps of Coryne sp. (Hydrozoa, Corynidae)

R. Golz
Institut fur Neuro- und Verhaltensbiologie, Universitat Munster, Germany

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.
