In hydromedusae such as Polyorchis, the best studied species, swimming is controlled by a group of neurons located in the inner nerve ring (Fig. 1C) (Anderson and Mackie, 1977; Spencer, 1978; 1982). There are from 3-15 of these neurons in any part of the nerve ring and in Polyorchis each measures up ...
