Hippocampal subregion abnormalities in schizophrenia: A systematic review of structural and physiological imaging studies [PDF]
Neuropsychopharmacology Reports, 2018 Aim The hippocampus is considered a key region in schizophrenia pathophysiology, but the nature of hippocampal subregion abnormalities and how they contribute to disease expression remain to be fully determined.

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 ...

Amyloid-β acts as a regulator of neurotransmitter release disrupting the interaction between synaptophysin and VAMP2. [PDF]
, 2012 BACKGROUND: It is becoming increasingly evident that deficits in the cortex and hippocampus at early stages of dementia in Alzheimer's disease (AD) are associated with synaptic damage caused by oligomers of the toxic amyloid-β peptide (Aβ42).

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 ...

Effect of scopolamine-based amnesia on the number of astrocytes in the rat's hippocampus [PDF]
, 2012 As neuron-astrocyte interactions play a crucial role in the adult brain, it is thought that astrocytes support learning and memory through specific mechanisms.

eLife, 2022 Standard models for spatial and episodic memory suggest that the lateral entorhinal cortex (LEC) and medial entorhinal cortex (MEC) send parallel independent inputs to the hippocampus, each carrying different types of information.

Hippocampal formation-inspired probabilistic generative model
Neural Networks, 2022 In building artificial intelligence (AI) agents, referring to how brains function in real environments can accelerate development by reducing the design space. In this study, we propose a probabilistic generative model (PGM) for navigation in uncertain environments by integrating the neuroscientific knowledge of hippocampal formation (HF) and the ...

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.
