Discrete states of synaptic strength in a stochastic model of spike-timing-dependent plasticity
TL;DR: The fixed-point dynamics of the model regulate the upward and downward transition probabilities so that these are on average equal, leading to a uniform distribution of synaptic strength states, consistent with some experimental data on ternary-strength synapses.

Synaptic scaling enables dynamically distinct short- and long-term memory formation

TL;DR: The interaction between plasticity and scaling provides an explanation for an established paradox where memory consolidation and destabilization critically depends on the exact order of learning and recall, and enables us to reproduce human-psychophysical results on the apparently paradoxical effect of memory destabilization due to memory recall.

Integration of exteroceptive and interoceptive information within the hippocampus: a computational study
TL;DR: It is suggested that distinct hippocampal subregions may be engaged in the representation of these different types of information, each stored apart in autoassociative memories but linked together in a heteroASSociative way.

Neural Associative Memory and the Willshaw–Palm Probability Distribution
TL;DR: This work compute and characterize the exact Willshaw–Palm distribution of the dendritic potentials for hetero-association, auto-ass association, and fixed and random pattern activity and reveals that, asymptotically, the binomial approximation becomes exact for almost any su...

Unsupervised Hebbian learning by recurrent multilayer neural networks for temporal hierarchical pattern recognition
TL;DR: An unsupervised learning scheme, which is Hebbian in the following sense: the strength of a synapse increases if the outputs of the presynaptic and postsynaptic neurons are identical and decreases otherwise.

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.

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.
