Theories on the functions of the hippocampal system are based largely on two fundamental
discoveries: the amnestic consequences of removing the hippocampus and associated …

The mechanisms for pattern completion and pattern separation are described in the context
of a theory of hippocampal function in which the hippocampal CA3 system operates as a …

Recent studies have reported the existence of hippocampal" time cells," neurons that fire at
particular moments during periods when behavior and location are relatively constant …

The hippocampal cognitive map is thought to be driven by distal visual cues and self-motion
cues. However, other sensory cues also influence place cells. Hence, we measured rat …

Cortical circuits are thought to multiplex firing rate codes with temporal codes that rely on
oscillatory network activity, but the circuit mechanisms that combine these coding schemes …

1. 1 Contexts The principal issue with which this monograph deals is the role of the
hippocam pus in establishing and using representations of contexts for information …

The human brain is, arguably, the most complex system in the universe. Its several hundred
billion elements, organized at various levels of description, permit organisms to interact …

According to schema theory as proposed by Piaget and Bartlett, learning involves the
assimilation of new memories into networks of preexisting knowledge, as well as alteration …

Hippocampal information processing is often described as two-state, with a place cell state
during movement and a reactivation state during stillness. Relatively little is known about …

A quantitative computational theory of the operation of the hippocampal CA3 system as an
autoassociation or attractor network used in episodic memory system is described. In this …
