Rapid formation of non-spatial hippocampal representations consistent with behavioral timescale synaptic plasticity is modulated by entorhinal input

Nature Communications
Behavioral timescale synaptic plasticity (BTSP) is a form of synaptic potentiation where a single plateau potential in hippocampal neurons forms a place field during spatial learning.

Synaptic Plasticity in the Entorhinal Cortex [PDF]

, 1995
The entorhinal cortex is reciprocally connected with both neocortical sensory areas and the hippocampal formation, and is thought to play a pivotal role in learning and memory.

Entorhinal cortex layer III Adgrl2 expression controls topographical circuit connectivity required for sequence learning

Translational Psychiatry
The entorhinal cortex and hippocampus are interconnected brain regions required for episodic learning and memory. For this functional encoding, correct assembly of specific synaptic connections across this circuit is critical during development. To guide

Hyperexcitability of entorhinal cortex and hippocampus after application of aminooxyacetic acid (AOAA) to layer III of the rat medial entorhinal cortex in vitro

, 1996
1. Injection of aminooxyacetic acid (AOAA) into the entorhinal cortex in vivo produces acute seizures and cell loss in medial entorhinal cortex. To understand these effects, AOAA was applied directly to the medial entorhinal cortex in slices containing ...

Carbachol induces fast oscillations in the medial but not in the lateral entorhinal cortex of the isolated guinea pig brain

, 1999
Fast oscillations at 25–80 Hz (gamma activity) have been proposed to play a role in attention-related mechanisms and synaptic plasticity in cortical structures.

The perforant pathway and CA3-Schaffer collateral afferents coordinate to regulate spatial learning

Communications Biology
The entorhinal-hippocampal system constitutes a pivotal neural circuit in the central nervous system. It is critically involved in processing spatial learning and memory.

Altered grid-like coding in early blind people

Nature Communications
Cognitive maps in the hippocampal-entorhinal system are central for the representation of both spatial and non-spatial relationships. Although this system, especially in humans, heavily relies on vision, the role of visual experience in shaping the ...
