Comparator and Buffer Memory

An Attempt to Integrate Two Models of Hippocampal Function

  • Chapter
The Hippocampus

Abstract

We have each recently proposed models of hippocampal function. The central concept of Gray’s model is that the septohippocampal system, together with the Papez circuit, functions as a comparator detecting departures from expectation in respect to both stimulus—stimulus and response—stimulus relationships. Rawlins’s model, in contrast, treats the hippocampal formation as a high-capacity, intermediate-term memory buffer. The principal aim of this chapter is to consider ways in which the two models may perhaps be integrated. We shall first present brief summaries of the two models (fuller accounts, including reviews of the data on which the models are based, are available elsewhere: Gray, 1982a,b; Rawlins, 1985). Gray’s model is given a relatively more detailed treatment as it is the more far-ranging.
