    Description

    The discovery of grid cells in the medial entorhinal cortex (mEC) encouraged investigation of the effect of the mEC on the hippocampus. Large lesions of the entorhinal cortex reduced theta oscillations, decreased the fraction of hippocampal CA1 place cells, and affected various features of place field properties. This study performed combined optogenetic and pharmacogenetic local and upstream inactivation...

    Description

    Lateral entorhinal cortex (LEC) performs important functions for episodic memory processing and coding for contextually salient elements of an environment or experience. This study combined functional circuit mapping and computational modeling to examine the cellular and circuit mechanisms by which long-range glutamatergic LEC projections influence the local activity in the hippocampus. This dataset...

    Description

    Previous studies indicated that the fraction of splitter fields is affected by the delay between responses in a spatial alternation task. This study demonstrated that memory and place field features of both pyramidal cells and interneurons in the hippocampus are interchangeable. They trained two groups of mice with and without delays in one or two environments and examined firing characteristics of...
