Although the Cognitive Map Theory and Memory Index Theory are not mutually exclusive, it still remained unclear on how to reconcile them. While it has been long assumed that IEG expression in the hippocampus captures activity of place cells, 24 the literature is riddle with contradictions. According to another theory, the hippocampus is an index of our brain and experiences. You could think of it as a book index that helps us find the information we are looking for in seconds. Interestingly, this theory says that the hippocampus stores the elements, not the whole experience. are very congruent with the Memory Index Theory of Teyler and DiScenna.22 Their 1986 paper, building on the Simple Memory Theory of David Marr23 as well as others, postulated a unique role of the hippocampus in episodic memory, suggesting that the hippocampus contains an index to provide rapid and Start studying Chapter 16: The Hippocampus Index & Episodic Memory.

Oct 5, 2015 Hippocampus is thus a kind of medium-term memory used to train the neocortex. Page 6. 10/05/15. Computational Models of Neural Systems. 6. In essence it was a theory of how the hippocampus contributes to episodic memory. As such it was a theory about (a) the role of the hip- pocampus in memory formation, (b) the nature of the memory trace, and (c) memory retrieval. This system is described by the Indexing Theory of Hippocampal Memory (Index Theory for short). Like a card catalog, or even a book’s index [gasp], this theory suggests that the hippocampus contains no real information beyond the synapses that trace back to the associated elements of a memory. There are a number of advantages to such a system. Here it is proposed that the role of the hippocampus is to form and retain an index of neocortical areas activated by experiential events. The hippocampal index, thus, represents those unique cortical regions activated by specific events. The neuronal mechanism underlying the memory index is hypothesized to be long-term potentiation. Abstract A little over 20 years ago, (Teyler and DiScenna, 1986 ; Behav Neurosci 100:147–152) proposed the hippocampal memory index theory. It offered an account of episodic memory based on the intrinsic organization of the hippocampus, its synaptic physiology and its anatomical relationship to other regions of the brain.
