The relative advantages of sparse versus distributed encoding for associative neuronal networks in the brain
TL;DR: The extent to which this statement is valid in general is discussed here, by considering some simple formal models of associative memory which include different neurobiological constraints.

Limits on the memory storage capacity of bounded synapses.
Stefano Fusi,L. F. Abbott +1 more
TL;DR: It is concluded that improving memory performance requires a more radical modification of the standard model of memory storage.

A network that uses few active neurones to code visual input predicts the diverse shapes of cortical receptive fields
Martin Rehn,Friedrich T. Sommer +1 more
TL;DR: A novel network model is proposed in which the number of active neurones, rather than mean neuronal activity, is limited and this form of hard sparseness economises cortical resources like synaptic memory and metabolic energy.
Journal ArticleDOI
Cortical-hippocampal interactions and cognitive mapping: A hypothesis based on reintegration of the parietal and inferotemporal pathways for visual processing
TL;DR: The hypothesis proposes that conditional associations between places and movements are established during learning about an environment and suggests how these compound movement/place representations could be combined with hippocampal spatial representations to account for the “blind” navigation phenomena.

Eligibility Traces and Plasticity on Behavioral Time Scales: Experimental Support of NeoHebbian Three-Factor Learning Rules.
TL;DR: In this paper, the role of synaptic eligibility traces in combination with a third factor as a biological implementation of the neoHebbian three-factor learning rules has been discussed in the context of synaptic plasticity.

Theory of Optical Information Storage in Solids
TL;DR: The theory of three-dimensional optical storage lends support to Beurle’s proposed mechanism of information storage in the brain, and makes three- dimensional storage very suitable for associative memories.

Holographic Model of Temporal Recall
TL;DR: It is shown that there is at least one other mathematical model, which is considered to be a closer analogue of holography, because it operates with triple products of the temporal function to be recognized or recalled.
Journal ArticleDOI
Improved holographic model of temporal recall.
TL;DR: The modified static system described here is an alternative to Longuet-Higgins' model and takes account of the weaknesses of the nervous system as well as of its powers to imitate human memory with models.

The Classification of Modifiable Synapses and Their Use In Models For Conditioning
TL;DR: It is argued that if the conditioning and memory mechanisms of the nervous system store information by means of modifiable synapses, some of these must be of class B or C, and if the models are to be given the property of extinction, classical conditioning requires modifiablesynapses of classes A and B or of class C.
