The Hippocampus and the Expression of Knowledge
This chapter will have three major themes. The first is that the attainment and expression of knowledge depend on the hippocampus by virtue of its involvement in retrieval processes. We shall define retrieval somewhat more restrictively than is normally the case. By retrieval we mean the selection of a single or small set of memories from among a larger set having some common content. Knowledge of any one object or stimulus can be only as rich or diverse as retrieval processes allow. We think retrieval processes are central to the kinds of processes that were thought to be responsible for learning by theorists in the cognitive tradition, as exemplified by Tolman (1948). We think a cognitive learning system, which includes the hippo campus, is present in the brain.
