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.

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.

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.

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.

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. If this is an ancestral feature of the hippocampus, then it is likely that the avian HF plays a similar role.

Progress in neurobiology, 2020 We advance a novel computational theory of the hippocampal formation as a hierarchical generative model that organizes sequential experiences, such as rodent trajectories during spatial navigation, into coherent spatiotemporal contexts.

A Novel In Vitro Preparation: the Intact Hippocampal Formation [PDF]
Neuron, 1997 The intact hippocampal formation (IHF) of neonatal or young rats can be kept alive for an extended period in a fully submerged chamber with excellent morphological preservation. Field or patch-clamp recordings, intracellular Ca2+ measurements, and 3-D reconstruction of biocytin-filled neurons can be performed routinely.

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 ...
