Grid Cells Form a Global Representation of Connected Environments. [PDF]
, 2015 The firing patterns of grid cells in medial entorhinal cortex (mEC) and associated brain areas form triangular arrays that tessellate the environment [1, 2] and maintain constant spatial offsets to each other between environments [3, 4].

Graded remapping of hippocampal ensembles under sensory conflicts
Cell Reports, 2021 Summary: Hippocampal place cells are thought to constitute a cognitive map of space derived from multimodal sensory inputs. Alteration of allocentric (visual) cues in a fixed environment is known to induce modulations of place cell activity to varying ...

Intracellular Dynamics of Virtual Place Cells [PDF]
Neural Computation, 2011 The pattern of spikes recorded from place cells in the rodent hippocampus is strongly modulated by both the spatial location in the environment and the theta rhythm. The phases of the spikes in the theta cycle advance during movement through the place field.

The contribution of bone marrow-derived cells to angiogenesis and lymphangiogenesis in murine models of carcinogenesis [PDF]
, 2009 Cancer is a class of diseases in which a group of cells display uncontrolled growth (division beyond the normal limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via ...

Neural Representation of Overlapping Path Segments and Reward Acquisitions in the Monkey Hippocampus
Frontiers in Systems Neuroscience, 2019 Disambiguation of overlapping events is thought to be the hallmark of episodic memory. Recent rodent studies have reported that when navigating overlapping path segments in the different routes place cell activity in the same overlapping path segments ...

LPMP: A Bio-Inspired Model for Visual Localization in Challenging Environments
Frontiers in Robotics and AI, 2022 Autonomous vehicles require precise and reliable self-localization to cope with dynamic environments. The field of visual place recognition (VPR) aims to solve this challenge by relying on the visual modality to recognize a place despite changes in the ...

Insensitivity of Place Cells to the Value of Spatial Goals in a Two-Choice Flexible Navigation Task
Journal of Neuroscience, 2019 Hippocampal place cells show position-specific activity thought to reflect a self-localization signal. Several reports also point to some form of goal encoding by place cells.
