Functional connectivity of the entorhinal–hippocampal space circuit
The mammalian space circuit is known to contain several functionally specialized cell types, such as place cells in the hippocampus and grid cells, head-direction cells and border cells in the medial entorhinal cortex (MEC). The interaction between the entorhinal and hippocampal spatial representations is poorly understood, however. We have developed an optogenetic strategy to identify function...
متن کاملA Circuit - Level Model of Hippocampal , Entorhinal and Prefrontal Dynamics Underlying Rodent Maze
Interactions between the hippocampus, parahippocampal regions and the prefrontal cortex are thought to underlie the formation, consolidation, and retrieval of short term memories and play an important role in the learning processes. To date, only conceptual models have been offered to explain the potential interactions among these regions, but their connectivity and synaptic regulation remain u...
متن کاملAn Entorhinal-Hippocampal Model for Simultaneous Cognitive Map Building
Hippocampal place cells and entorhinal grid cells have been hypothesized to be able to form map-like spatial representation of the environment, namely cognitive map. In most prior approaches, either neural network methods or only hippocampal models are used for building cognitive maps, lacking biological fidelity to the entorhinal-hippocampal system. This paper presents a novel computational mo...
متن کاملHippocampal conjunctive encoding, storage, and recall: avoiding a trade-off.
The hippocampus and related structures are thought to be capable of 1) representing cortical activity in a way that minimizes overlap of the representations assigned to different cortical patterns (pattern separation); and 2) modifying synaptic connections so that these representations can later be reinstated from partial or noisy versions of the cortical activity pattern that was present at th...
متن کامل[Hippocampal-prefrontal cortical circuit and working memory].
The study on learning and memory is one of the striking subjects in neuroscience today. In the cerebral cortex, it is has been proved that, the hippocampus, the prefrontal cortex and the hippocampal-prefrontal cortical circuit are important to working memory. In this paper, we review findings of the anatomical and electrophysiological characteristics of the hippocampal-prefrontal cortical circu...
