A place for place cells in post-stroke cognitive impairment. [PDF]
Trends NeurosciIn a recent study, Heiser et al. showed that hippocampal place cell stability and spatial encoding were disrupted in mice after brain-wide microstrokes. These findings suggest that hippocampal neurons are particularly vulnerable to dysfunction after stroke, even in the absence of local lesions.

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.

Slow Turning Lateral Vessel Bioreactor Improves Embryoid Body Formation and Cardiogenic Differentiation of Mouse Embryonic Stem Cells. [PDF]
, 2013 Embryonic stem cells (ESCs) have the ability to form aggregates, which are called embryoid bodies (EBs). EBs mimic early embryonic development and are commonly produced for cardiomyogenesis.

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 ...

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 ...
