Design Principles of the Hippocampal Cognitive Map
Hippocampal place fields have been shown to reflect behaviorally relevant aspects of space. For instance, place fields tend to be skewed along commonly traveled directions, they cluster around rewarded locations, and they are constrained by the geometric structure of the environment. We hypothesize a set of design principles for the hippocampal cognitive map that explain how place fields repres...
متن کاملHippocampal Sequences and the Cognitive Map
Ensemble activity in the hippocampus is often arranged in temporal sequences of spiking. Early theoretical and experimental work strongly suggested that hippocampal sequences functioned as a neural mechanism for memory consolidation, and recent experiments suggest a causal link between sequences during sleep and mnemonic processing. However, in addition to sleep, the hippocampus expresses seque...
متن کاملLandmark Arrays and the Hippocampal Cognitive Map
Animal navigation can be simultaneously studied externally, at the level of actions in the world, and internally, at the level of individual neuron firings. In this paper we describe a computational theory of rodent navigation that is constrained by data at both these levels. We report results of computer simulations of a split landmark array task that lead to interesting predictions about the ...
متن کاملDevelopment of the hippocampal cognitive map in preweanling rats.
Orienting in large-scale space depends on the interaction of environmental experience and preconfigured, possibly innate, constructs. Place, head-direction, and grid cells in the hippocampal formation provide allocentric representations of space. Here we show how these cognitive representations emerge and develop as rat pups first begin to explore their environment. Directional, locational, and...
متن کاملSupplemental Information for Design Principles of the Hippocampal Cognitive Map
The SR-based critic learns an estimate of the value function, using the SR as its feature representation. Unlike standard actor-critic methods, the critic does not use reward-based temporal difference errors to update its value estimate; instead, it relies on the fact that the value function is given by V (s) = ∑ s′ M(s, s ′)R(s′), where M is the successor representation andR is the expected re...
