Lateral Entorhinal Cortex is Critical for Novel Object-Context Recognition
Episodic memory incorporates information about specific events or occasions including spatial locations and the contextual features of the environment in which the event took place. It has been modeled in rats using spontaneous exploration of novel configurations of objects, their locations, and the contexts in which they are presented. While we have a detailed understanding of how spatial loca...
متن کاملLateral entorhinal cortex is necessary for associative but not nonassociative recognition memory
The lateral entorhinal cortex (LEC) provides one of the two major input pathways to the hippocampus and has been suggested to process the nonspatial contextual details of episodic memory. Combined with spatial information from the medial entorhinal cortex it is hypothesised that this contextual information is used to form an integrated spatially selective, context-specific response in the hippo...
متن کاملCellular properties of principal neurons in the rat entorhinal cortex. I. The lateral entorhinal cortex.
The lateral entorhinal cortex (LEC) provides a major cortical input to the hippocampal formation, equaling that of the medial entorhinal cortex (MEC). To understand the functional contributions made by LEC, basic knowledge of individual neurons, in the context of the intrinsic network, is needed. The aim of this study is to compare physiological and morphological properties of principal neurons...
متن کاملA neural circuit analysis of visual recognition memory: role of perirhinal, medial, and lateral entorhinal cortex.
Using a continuous recognition memory procedure for visual object information, we sequentially presented rats with eight novel objects and four repeated objects (chosen from the 8). These were selected from 120 different three-dimensional objects of varying sizes, shapes, textures, and degree of brightness. Repeated objects had lags ranging from 0 to 4 (from 0 to 4 different objects between the...
متن کاملTraces of Experience in the Lateral Entorhinal Cortex
A growing body of evidence suggests that memories are stored in the hippocampus by integrating spatial information from specialized cell types in the medial entorhinal cortex (MEC) with nonspatial information from cells in the lateral entorhinal cortex (LEC). LEC neurons show little spatial modulation when rats run in empty open-field environments but fire in the vicinity of discrete objects, s...
