Simple memory: a theory for archicortex

Memory, modelling and Marr: a commentary on Marr (1971) ‘Simple memory: a theory of archicortex’

David Marr's theory of the archicortex, a brain structure now more commonly known as the hippocampus and hippocampal formation, is an epochal contribution to theoretical neuroscience. Addressing the problem of how information about 10 000 events could be stored in the archicortex during the day so that they can be retrieved using partial information and then transferred to the neocortex overnig...

Marr's Theory of the Hippocampus as a Simple Memory: Decades of Subsequent Research Suggest It Is Not That Simple

Marr's 1971 simple memory theory of archicortex set the stage for over four decades of subsequent research on the medial temporal lobe memory system. Marr’s ideas contributed fundamentally to current computational models of the hippocampus. In particular, this theory led to the widely held view of the hippocampus as a temporary memory store that accurately memorizes events by creating orthogona...

Quantitative analysis of a Schaffer collateral model

Recent advances in techniques for the formal analysis of neural networks (Amit et al., 1987; Gardner, 1988; Treves, 1990; Nadal and Parga, 1993) have introduced the possibility of detailed quantitative analyses of real brain circuitry. This approach is particularly appropriate for regions such as the hippocampus, which show distinct structure and for which the microanatomy is relatively simple ...

A MODIFIED STEFFENSEN'S METHOD WITH MEMORY FOR NONLINEAR EQUATIONS

In this note, we propose a modification of Steffensen's method with some free parameters. These parameters are then be used for further acceleration via the concept of with memorization. In this way, we derive a fast Steffensen-type method with memory for solving nonlinear equations. Numerical results are also given to support the underlying theory of the article.
