Strategies for the Study of the Coelenterate Brain

  • L. M. Passano


Some years ago it was fashionable to hope that the nervous system of some coelenterate would be simple enough so that it could be ‘described completely’, either functionally, morphologically or, ideally, both. But now, for at least three reasons, this approach has palled. In the first place, the nervous system seems more complex, with the passing of the simplistic view that the functional units are always neurons, linked together by standardized junctions. At least in other, ‘higher’ forms, there are many different kinds of synapses, even within single neurons; single neurons can subserve more than one function in an organism, even at the same time. Secondly, non-nervous components in coelenterate coordinating systems are now known to be basic elements in behavioral control (Mackie, 1970). Finally, behavioral studies always reveal greater complexity than was previously imagined.
