WEISKRANTZ Department of Experimental Psychology, University of OxJord We have a very exciting topic for this symposium: we also have a great number of different disciplines and approaches. We hope that out of the entire discussion some kind of synthesis will emerge, or at least some agreement about where and why we disagree. I personally hope that we can keep certain broad issues in mind during the symposium. The striking aspect of the hippocampus is the anatomical elegance of its structure, revealed in detail in the past few years. In contrast there is really appalling ignorance about what this elegance means. I am not sure that the septa1 area is quite so elegant in appearance but the hippocampus certainly is. Anatomical information will be presented to us. In recent years certain favourite anatomical connections have been stressed in discussions of the septo-hippocampal system, but there are older connections too: anatomists keep on adding connections; they very rarely subtract any ! These ‘older’ connections, between for example the hippocampus and thalamus, are rarely stressed now and it may be worth reminding ourselves that we are dealing with a rather more complex anatomical system than just the pathways that we happen to be interested in at the moment. We shall be given information on neurotransmitters, and it is worth asking ourselves why God made so many different transmitters when presumably it would be possible for all synapses to work on one transmitter, if the only function is to get signals from one neuron to another. The questicn here is what are the functional implications of a dependence on a particular trans- mitter, if there is one, in this particular anatomical system. We shall hear electrophysiological information also, and I hope in discussion we can ask ourselves.how we go from the single cell, which is the favourite unit of analysis these days, to populations of cells and their organizational structure. That is a standard problem but by no means a simple one to overcome. 1 2 L. WEISKRANTZ We shall also be discussing function. There are a great many different approaches to the question of function. Historically, the suggested role of the hippocampus in memory is one with which we are all familiar. We are also familiar with its suggested role in emotional behaviour-in frustration and punishment-and relevant to that will be information on the endo- crinological aspects of the hippocampus. We know now about its possible role in spatial functions. We know that it seems to have some connection with voluntary movement. We know about its suggested role in various kinds of disinhibitory and perseverative behaviour, and in habituation. I hope we can direct our attention to three questions: first, is it possible to subsume all these different kinds of functions under a single heading? Is there some fundamental scheme in the Platonic sense which we see the shadows of, from time to time, in the various hypotheses that have been put forward? It would be interesting and important to see whether we can get agreement on that. The second question is: what are the ways in which the different suggested functions can be studied independently? Is an animal, for example, who is impaired on spatial function going to be impaired on various other aspects of'behaviour because he has a spatial deficit? We must know the answer to this before we can decide whether we are dealing with several independent functions. Finally, the third question is related to the second but is not quite the same: the title of the symposium contains the words 'septo-hippocampal system'. By the end, we may want to know whether we are in fact dealing with systems in the plural, rather than one single system.
