Morphometry Difference of the Hippocampal Formation Between Blind and Sighted Individuals [PDF]

Frontiers in Neuroscience, 2021
The detailed morphometry alterations of the human hippocampal formation (HF) for blind individuals are still understudied. 50 subjects were recruited from Yantai Affiliated Hospital of Binzhou Medical University, including 16 congenital blindness, 14 ...

The hippocampal formation and action at a distance. [PDF]

Proc Natl Acad Sci U S A, 2021
Significance This article proposes an overarching hypothesis about the function of the hippocampal formation, namely, that it enables organisms to bridge significant spatial and temporal gaps in experience and is thereby deeply involved in aspects of spatial cognition, event segmentation, and memory.

Chick Hippocampal Formation Displays Subdivision- and Layer-Selective Expression Patterns of Serotonin Receptor Subfamily Genes [PDF]

Frontiers in Physiology, 2022
Hippocampal formation (HF) plays a key role in cognitive and emotional processing in mammals. In HF neural circuits, serotonin receptors (5-HTRs) modulate functions related to cognition and emotion. To understand the phylogenetic continuity of the neural

Vascular patterns of the rat hippocampal formation [PDF]

Experimental Neurology, 1976
Abstract Little is known of the course and distribution of blood vessels supplying and draining the hippocampus. Such information could be of value in designing and evaluating lesion and ablation experiments and may reflect spatial properties of neurons.

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.

cFOS as a biomarker of activity maturation in the hippocampal formation. [PDF]

Front Neurosci, 2023
We explored the potential for cFOS expression as a marker of functional development of “resting-state” waking activity in the extended network of the hippocampus and entorhinal cortex. We examined sleeping and awake mice at (P)ostnatal days 5, 9, 13, and 17 as well as in adulthood.

Effects of aerobic exercise on hippocampal formation volume in people with schizophrenia - a systematic review and meta-analysis with original data from a randomized-controlled trial. [PDF]

Psychol Med
Background: The hippocampal formation represents a key region in the pathophysiology of schizophrenia. Aerobic exercise poses a promising add-on treatment to potentially counteract structural impairments of the hippocampal formation and associated ...

Postnatal Development of the Primate Hippocampal Formation [PDF]

Developmental Neuroscience, 2006
The hippocampal formation is a multicomponent region of the medial temporal lobe preferentially involved in declarative and relational memory processing. Behavioral studies have suggested a protracted functional maturation of these structures in primates, and postnatal developmental abnormalities in the hippocampal formation are thought to contribute ...

Walking and Hippocampal Formation Volume Changes: A Systematic Review [PDF]

Brain Sciences
Background/Objectives: Sustaining the human brain’s hippocampus from atrophy throughout ageing is critical. Exercise is proven to be effective in promoting adaptive hippocampal plasticity, and the hippocampus has a bidirectional relationship with the ...

Morphological Variations of Hippocampal Formation in Epilepsy

Pediatric Neurology Briefs, 2013
Researchers at Hospital Sao Paulo and other centers in Brazil compared the hippocampal formation (HF) morphology of healthy asymptomatic individuals (n=30) with that of patients with mesial temporal lobe epilepsy and hippocampal sclerosis (MTLE-HS)(n=68),
