Sparse odor representation and olfactory learning.
Iori Ito,Rose Chik-ying Ong,Rose Chik-ying Ong,Baranidharan Raman,Baranidharan Raman,Mark Stopfer +5 more
TL;DR: It is found that odor-elicited spiking in these cells ended well before the reinforcement was delivered, and Hebbian spike timing–dependent plasticity in Kenyon cells alone cannot underlie this learning.

Modeling the temporal dynamics of it neurons in visual search: A mechanism for top-down selective attention
Marius Usher,Ernst Niebur +1 more
TL;DR: A neural model for object-oriented attention in which various visual stimuli are represented by competing, mutually inhibitory, cell assemblies is proposed, which suggests that such a process may be used by the visual system for selecting an expected target (appearing at an uncertain location) among distractors.
Journal ArticleDOI
Re-evaluating circuit mechanisms underlying pattern separation
TL;DR: It is argued that the dimensionality of the space available for population codes representing sensory and motor information provides a common framework for understanding pattern separation and helps facilitate associative learning in the presence of trial-to-trial variability.
Journal ArticleDOI
Internal representations for associative memory
TL;DR: A class of feed forward neural network models for associative content addressable memory (ACAM) which utilize sparse internal representations for stored data and study two classes of internal label representations: the unary representation and various sparse, distributed representations.

Neural trees: a new tool for classification
J. A. Sirat,Jean-Pierre Nadal +1 more
TL;DR: A new classifier based on neural network techniques, inspired from a growth algorithm, recently introduced for feedforward neural networks, which is easily and efficiently extended to classification in a multiclass probl...

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.
