bioRxiv, 2020 The hippocampus is thought to guide navigation by forming a cognitive map of space. However, the behavioral demands for such a map can vary depending on particular features of a given environment.

Optimal Population Codes for Space: Grid Cells Outperform Place Cells [PDF]
, 2012 Rodents use two distinct neuronal coordinate systems to estimate their position: place fields in the hippocampus and grid fields in the entorhinal cortex.

Impaired spatial memory codes in a mouse model of Rett syndrome
eLife, 2018 The Mecp2+/- mouse model recapitulates many phenotypes of patients with Rett syndrome (RTT), including learning and memory deficits. It is unknown, however, how the disease state alters memory circuit functions in vivo in RTT mice.

Boundary vector cells in the subiculum of the hippocampal formation [PDF]
, 2009 Stretching a familiar rectangular environment along one axis results in a stretching of place cell (PC) firing fields (“place fields”) along the same axis (O’Keefe and Burgess, 1996).

The Growing Evidence for the Importance of the Otoliths in Spatial Memory
Frontiers in Neural Circuits, 2019 Many studies have demonstrated that vestibular sensory input is important for spatial learning and memory. However, it has been unclear what contributions the different parts of the vestibular system – the semi-circular canals and otoliths – make to ...

eLife, 2019 Most vertebrates use active sensing strategies for perception, cognition and control of motor activity. These strategies include directed body/sensor movements or increases in discrete sensory sampling events. The weakly electric fish, Gymnotus sp., uses

Biomimetic SLAM Algorithm Based on Growing Self-Organizing Map
IEEE Access, 2021 A Biomimetic SLAM Algorithm Based on Growing Self-Organizing Map (GSOM-BSLAM), inspired by spatial cognitive mechanism of mammalian hippocampus, is proposed to resolve uncertainty problems in location identification and lack of real-time performance in ...

Differential Impact of Acute and Chronic Stress on CA1 Spatial Coding and Gamma Oscillations
Frontiers in Behavioral Neuroscience, 2021 Chronic and acute stress differentially affect behavior as well as the structural integrity of the hippocampus, a key brain region involved in cognition and memory.

Place, space and memory cells [PDF]
Current Biology, 2012 SummarySelf-localization and navigation are critical functions for the survival of mobile animals. By processing sensory information such as landmarks and environmental features, as well as keeping track of the path they have taken, animals are able to remain oriented as they explore the world, learning what resources are where and planning how to ...

Frontiers in Cellular Neuroscience, 2018 Hippocampal place cells are key to spatial representation and spatial memory processing. They fire at specific locations in a space (place fields) and fire in precise patterns during theta sequences and during ripple-associated replay events.
