Ionic Currents of the Scyphozoa

Scyphozoans are members of the phylum Cnidaria and, according to Werner (1973), are the second most primitive extant class of this, the most primitive group of animals to possess a recognizable nervous system. Their nervous systems are, for the most part, composed almost entirely of diffuse two-dimensional plexuses of neurons, nerve nets (Passano, 1982), the most prominent of which is the motor nerve net (Anderson and Schwab, 1981), a diffuse plexus of large bipolar neurons that transmits motor activity from marginal pacemakers to the swimming muscle. This nerve net was previously called the Giant Fiber Nerve Net (Horridge, 1954), on account of the unusually large size of its component neurons.
