Object-vector coding in the medial entorhinal cortex [PDF]

Nature, 2019
The hippocampus and the medial entorhinal cortex are part of a brain system that maps self-location during navigation in the proximal environment1,2. In this system, correlations between neural firing and an animal's position or orientation are so evident that cell types have been given simple descriptive names, such as place cells3, grid cells4 ...

Minute-scale oscillatory sequences in medial entorhinal cortex. [PDF]

Nature, 2023
AbstractThe medial entorhinal cortex (MEC) hosts many of the brain’s circuit elements for spatial navigation and episodic memory, operations that require neural activity to be organized across long durations of experience1. Whereas location is known to be encoded by spatially tuned cell types in this brain region2,3, little is known about how the ...

Medial entorhinal cortex activates in a traveling wave in the rat. [PDF]

Elife, 2020
Traveling waves are hypothesized to support the long-range coordination of anatomically distributed circuits. Whether separate strongly interacting circuits exhibit traveling waves remains unknown. The hippocampus exhibits traveling ‘theta’ waves and interacts strongly with the medial entorhinal cortex (MEC). To determine whether the MEC also activates

GABAergic Presubicular Projections to the Medial Entorhinal Cortex of the Rat [PDF]

The Journal of Neuroscience, 1997
We characterized presubicular neurons giving rise to bilateral projections to the medial entorhinal cortex (MEA) of the rat. Retrograde labeling of presubiculo–entorhinal projections with horseradish peroxidase and subsequent GABA immunocytochemistry revealed that 20–30% of the ipsilaterally projecting neurons are GABAergic. No GABAergic projections to

Topography of Head Direction Cells in Medial Entorhinal Cortex [PDF]

Current Biology, 2014
Neural circuits in the medial entorhinal cortex (MEC) support translation of the external environment to an internal map of space, with grid and head direction neurons providing metrics for distance and orientation.We show here that head direction cells in MEC are organized topographically.

Lateral entorhinal cortex is necessary for associative but not nonassociative recognition memory [PDF]

, 2013
This work was supported by BBSRC [Grant number BB/I019367/1]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 ...

The medial entorhinal cortex keeps Up

Nature Neuroscience, 2012
A study reveals that medial entorhinal cortex layer III spiking dynamics shape the neocortical-hippocampal dialog during Up-Down state fluctuations in slow-wave sleep that may contribute to memory consolidation.

Relaxin-3 Innervation From the Nucleus Incertus to the Parahippocampal Cortex of the Rat

Frontiers in Neuroanatomy, 2021
Spatial learning and memory processes depend on anatomical and functional interactions between the hippocampus and the entorhinal cortex. A key neurophysiological component of these processes is hippocampal theta rhythm, which can be driven from ...

Integrating visual and tactile information in the perirhinal cortex [PDF]

, 2009
By virtue of its widespread afferent projections, perirhinal cortex is thought to bind polymodal information into abstract object-level representations.

The topology of connections between rat prefrontal and temporal cortices [PDF]

, 2015
Understanding the structural organization of the prefrontal cortex (PFC) is an important step toward determining its functional organization. Here we investigated the organization of PFC using different neuronal tracers.
