Hippocampal place cells encode global location but not connectivity in a complex space.
Curr Biol, 2021 Summary Flexible navigation relies on a cognitive map of space, thought to be implemented by hippocampal place cells: neurons that exhibit location-specific firing.

Linear Self-Motion Cues Support the Spatial Distribution and Stability of Hippocampal Place Cells [PDF]
Current Biology, 2018 The vestibular system provides a crucial component of place-cell and head-direction cell activity [1-7]. Otolith signals are necessary for head-direction signal stability and associated behavior [8, 9], and the head-direction signal's contribution to ...

Navigating with grid and place cells in cluttered environments. [PDF]
Hippocampus, 2020 Hippocampal formation contains several classes of neurons thought to be involved in navigational processes, in particular place cells and grid cells. Place cells have been associated with a topological strategy for navigation, while grid cells have been ...

A Positioning Method Based on Place Cells and Head-Direction Cells for Inertial/Visual Brain-Inspired Navigation System [PDF]
Sensors, 2021 Mammals rely on vision and self-motion information in nature to distinguish directions and navigate accurately and stably. Inspired by the mammalian brain neurons to represent the spatial environment, the brain-inspired positioning method based on multi ...

Scopolamine Impairs Spatial Information Recorded With “Miniscope” Calcium Imaging in Hippocampal Place Cells [PDF]
Frontiers in Neuroscience, 2021 The hippocampus and associated cholinergic inputs have important roles in spatial memory in rodents. Muscarinic acetylcholine receptors (mAChRs) are involved in the communication of cholinergic signals and regulate spatial memory. They have been found to

Place Cells, Grid Cells, and Memory [PDF]
Cold Spring Harbor Perspectives in Biology, 2015 The hippocampal system is critical for storage and retrieval of declarative memories, including memories for locations and events that take place at those locations. Spatial memories place high demands on capacity. Memories must be distinct to be recalled without interference and encoding must be fast.

A memory model of rodent spatial navigation in which place cells are memories arranged in a grid and grid cells are non-spatial [PDF]
eLifeA theory and neurocomputational model are presented that explain grid cell responses as the byproduct of equally dissimilar hippocampal memories. On this account, place and grid cells are best understood as the natural consequence of memory encoding and ...

From grid cells and visual place cells to multimodal place cell: a new robotic architecture
Frontiers in Neurorobotics, 2015 In the present study, a new architecture for the generation of grid cells (GC) was implemented on a real robot. In order to test this model a simple place cell (PC) model merging visual PC activity and GC was developed. GC were first built from a simple "several to one" projection (similar to a modulo operation) performed on a neural field coding for ...
