iScience, 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 ...

Brain 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.

Frontiers 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.

Nature 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).

Entorhinal denervation induces homeostatic synaptic scaling of excitatory postsynapses of dentate granule cells in mouse organotypic slice cultures [PDF]
, 2012 Denervation-induced changes in excitatory synaptic strength were studied following entorhinal deafferentation of hippocampal granule cells in mature (≥3 weeks old) mouse organotypic entorhino-hippocampal slice cultures.

Mouse entorhinal cortex encodes a diverse repertoire of self-motion signals
Nature Communications, 2021 Here, the authors show that mouse medial entorhinal cortex encodes three-dimensional head movement as well as eye position and velocity. These self-motion signals are represented conjunctively in individual neurons alongside body position, running speed,

Shared rhythmic subcortical GABAergic input to the entorhinal cortex and presubiculum
eLife, 2018 Rhythmic theta frequency (~5–12 Hz) oscillations coordinate neuronal synchrony and higher frequency oscillations across the cortex. Spatial navigation and context-dependent episodic memories are represented in several interconnected regions including the

Medial Entorhinal Cortex Selectively Supports Temporal Coding by Hippocampal Neurons [PDF]
, 2017 Recent studies have shown that hippocampal “time cells” code for sequential moments in temporally organized experiences. However, it is currently unknown whether these temporal firing patterns critically rely on upstream cortical input. Here we employ an

Alexandria Journal of Medicine, 2017 Background: Tramadol is a centrally acting synthetic analgesic agent with opioid activity. Tramadol is used to treat moderate to severe pain. The entorhinal cortex has initially attracted attention because of its strong reciprocal connections with the ...
