Ontogeny of neural circuits underlying spatial memory in the rat [PDF]

open access: yes, 2012
Spatial memory is a well-characterized psychological function in both humans and rodents. The combined computations of a network of systems including place cells in the hippocampus, grid cells in the medial entorhinal cortex and head direction cells ...

Electrical Stimulation of the Lateral Entorhinal Cortex Causes a Frequency-Specific BOLD Response Pattern in the Rat Brain

open access: yesFrontiers in Neuroscience, 2019
Although deep brain stimulation of the entorhinal cortex has recently shown promise in the treatment of early forms of cognitive decline, the underlying neurophysiological processes remain elusive.

Afferent Projections to Area Prostriata of the Mouse

open access: yesFrontiers in Neuroanatomy, 2020
Area prostriata plays important roles in fast detection and analysis of peripheral visual information. It remains unclear whether the prostriata directly receives and integrates information from other modalities.

Re-expression of CA1 and entorhinal activity patterns preserves temporal context memory at long timescales

open access: yesNature Communications, 2023
Converging, cross-species evidence indicates that memory for time is supported by hippocampal area CA1 and entorhinal cortex. However, limited evidence characterizes how these regions preserve temporal memories over long timescales (e.g., months).

Theta dominates cross-frequency coupling in hippocampal-medial entorhinal circuit during awake-behavior in rats

open access: yesiScience, 2022
Summary: Hippocampal theta and gamma rhythms are hypothesized to play a role in the physiology of higher cognition. Prior research has reported that an offset in theta cycles between the entorhinal cortex, CA3, and CA1 regions promotes independence of ...

Microcircuits of Functionally Identified Neurons in the Rat Medial Entorhinal Cortex [PDF]

open access: yesNeuron, 2011
Extracellular recordings have elucidated spatial neural representations without identifying underlying microcircuits. We labeled neurons juxtacellularly in medial entorhinal cortex of freely moving rats with a friction-based, pipette-stabilization system. In a linear maze novel to the animals, spatial firing of superficial layer neurons was reminiscent

Medial temporal pathways for contextual learning: Network c- mapping in rats with or without perirhinal cortex lesions

open access: yesBrain and Neuroscience Advances, 2017
Background: In the rat brain, context information is thought to engage network interactions between the postrhinal cortex, medial entorhinal cortex, and the hippocampus.

Shedding light on stellate cells

open access: yeseLife, 2018
The relationship between grid cells and two types of neurons found in the medial entorhinal cortex has been clarified.

Relative contributions of CA3 and medial entorhinal cortex to memory in rats [PDF]

open access: yesFrontiers in Behavioral Neuroscience, 2014
The hippocampal CA1 field processes spatial information, but the relative importance of intra- vs. extra-hippocampal sources of input into CA1 for spatial behavior is unclear. To characterize the relative roles of these two sources of input, originating in the hippocampal field CA3 and in the medial entorhinal cortex (MEC), we studied effects of ...

ARM-Cortex M3-Based Two-Wheel Robot for Assessing Grid Cell Model of Medial Entorhinal Cortex: Progress towards Building Robots with Biologically Inspired Navigation-Cognitive Maps

open access: yesJournal of Robotics, 2017
This article presents the implementation and use of a two-wheel autonomous robot and its effectiveness as a tool for studying the recently discovered use of grid cells as part of mammalian’s brains space-mapping circuitry (specifically the medial ...
