Pattern Completion and Pattern Separation Mechanisms in the Hippocampus
There is great interest in how pattern separation and pattern completion in the hippocampus contribute to its functions in memory and spatial function (Giocomo et al. 2011; Jezek et al. 2011; Leutgeb et al. 2007; McHugh et al. 2007; Nakashiba et al. 2012; Nakazawa et al. 2002, 2003; Wills et al. 2005), and among those who have made many contributions in this area are Ray Kesner and his colleagu...
متن کاملPattern separation, completion, and categorisation in the hippocampus and neocortex.
The mechanisms for pattern completion and pattern separation are described in the context of a theory of hippocampal function in which the hippocampal CA3 system operates as a single attractor or autoassociation network to enable rapid, one-trial, associations between any spatial location (place in rodents, or spatial view in primates) and an object or reward, and to provide for completion of t...
متن کاملPattern separation, pattern completion, and new neuronal codes within a continuous CA3 map.
The hippocampal CA3 subregion is critical for rapidly encoding new memories, which suggests that neuronal computations are implemented in its circuitry that cannot be performed elsewhere in the hippocampus or in the neocortex. Recording studies show that CA3 cells are bound to a large degree to a spatial coordinate system, while CA1 cells can become more independent of a map-based mechanism and...
متن کاملPattern separation and pattern completion in the hippocampal system. Introduction to the Special Issue.
For a memory system such as the hippocampus in which asso-ciatively modifiable recurrent collateral connections between a population of neurons such as the CA3 pyramidal cells are believed, it is important that the memory representations to be stored are as orthogonal or uncorrelated as possible, to maximize the storage capacity. Only if the sets of neuronal firing, each representing a differen...
