Cortico-Hippocampal Interplay and the Representation of Contexts in the Brian

This is a republication of a work originally published in 1991, still largely up-to-date. It outlines a theory of interaction between hippocampus and cerebral neocortex based on the formation and use of phase-locked loops between the two structures using available axonal delay lines. The scheme serves as a means of indexing and retrieving the information stored in the cerebral cortex.
