Vector trace cells in the subiculum of the hippocampal formation. [PDF]

Nat Neurosci, 2021
AbstractSuccessfully navigating in physical or semantic space requires a neural representation of allocentric (map-based) vectors to boundaries, objects, and goals. Cognitive processes such as path-planning and imagination entail recall of vector representations, but evidence of neuron-level memory for allocentric vectors has been lacking.

Spatial goal coding in the hippocampal formation [PDF]

Neuron, 2022
The mammalian hippocampal formation contains several distinct populations of neurons involved in representing self-position and orientation. These neurons, which include place, grid, head direction, and boundary cells, are thought to collectively instantiate cognitive maps supporting flexible navigation.

Mechanism of Mongolian Medicine Eerdun Wurile in Improving Postoperative Cognitive Dysfunction Through Activation of the PI3K Signaling Pathway

Frontiers in Neuroscience, 2022
ObjectiveTo study the effect of Eerdun Wurile (EW), a traditional Mongolian medicine, on the cognitive function of rats by activating the IRS-PI3K-AKT-GLUT4 pathway in an animal model of postoperative cognitive dysfunction (POCD).MethodsFifty clean-grade

Structural organization of the rat hyppocampal formation

Сибирский научный медицинский журнал, 2023
The review examines the historical aspects of the hippocampus nomenclature. Its anatomical study began by the ancient Greeks, who called the unusual–looking structure a “ram’s horn” – cornu ammonis. The term “hippocampus” (ancient Greek: ἱππόκαμπος, from

Corticosteroids: Sculptors of the Hippocampal Formation [PDF]

Reviews in the Neurosciences, 2002
The influence of corticosteroids on hippocampus-dependent learning and memory processes is now indisputable. On the other hand, closer scrutiny of early studies together with interpretations from newer studies would suggest that the proposition that corticosteroid-induced hippocampal cell death accounts fully for the associated cognitive deficits is ...

Cell Proliferation in the Adult Chicken Hippocampus Correlates With Individual Differences in Time Spent in Outdoor Areas and Tonic Immobility

Frontiers in Veterinary Science, 2020
Access to outdoor areas is provided as a means of enhancing welfare in commercial systems for laying hens (Gallus gallus domesticus), but substantial individual differences exist in their proportional use.

Morphometric characteristics of the neurons of the human subiculum proper [PDF]

Archives of Biological Sciences, 2012
The human subiculum is a significant part of the hippocampal formation positioned between the hippocampus proper and the entorhinal and other cortices.

Hippocampal Global Remapping Can Occur without Input from the Medial Entorhinal Cortex. [PDF]

, 2018
The high storage capacity of the episodic memory system relies on distinct representations for events that are separated in time and space. The spatial component of these computations includes the formation of independent maps by hippocampal place cells ...

Spatial representation in the hippocampal formation: a history [PDF]

Nature Neuroscience, 2017
Since the first place cell was recorded and the cognitive-map theory was subsequently formulated, investigation of spatial representation in the hippocampal formation has evolved in stages. Early studies sought to verify the spatial nature of place cell activity and determine its sensory origin.
