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.

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.

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.

A novel somatosensory spatial navigation system outside the hippocampal formation. [PDF]
Cell Res, 2021 Spatially selective firing of place cells, grid cells, boundary vector/border cells and head direction cells constitutes the basic building blocks of a canonical spatial navigation system centered on the hippocampal-entorhinal complex.

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 ...

Configural association theory: The role of the hippocampal formation in learning, memory, and amnesia [PDF]
Psychobiology, 1989 It is proposed that the hippocampal formation makes a unique contribution to memory by providing the neural basis for the initial acquisition and storage of configural associations among events. A distinction is made between two kinds of memory processes:

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.

The Avian Hippocampal Formation and the Stress Response [PDF]
Brain, Behavior and Evolution, 2017 Though widely studied for its function in memory and navigation, the hippocampal formation (HF) in mammals also plays an important role in regulating the stress response.

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

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.
