Electrophysiological Correlates of Feeding Behavior in Tubularia

  • Norman B. Rushforth


Several studies have described spontaneous electrical activity in hydroids. Some of the observed pulses have common features in that they are relatively large in amplitude, on the order of several millivolts, have long duration, up to several hundred milliseconds, and may be externally recorded from large blocks of tissue. Such potentials, which are associated with simple recurrent behavioral activity, were first observed in Tubularia by Josephson (1962), in Hydra by Passano and McCullough (1962), in Obelia by Morin and Cooke (1971), in Corymorpha by Ball (1973).
