CoRR, 2023 A neuromorphic SLAM system shows potential for more efficient implementation than its traditional counterpart. We demonstrate a mixed-mode implementation for spatial encoding neurons including theta cells, vector cells, and place cells. Together, they form a biologically plausible network that could reproduce the localization functionality of place ...

Place cells and place navigation [PDF]
Proceedings of the National Academy of Sciences, 1997 The assumption that hippocampal place cells (PCs) form the neural substrate of cognitive maps can be experimentally tested by comparing the effect of experimental interventions on PC activity and place navigation. Conditions that interfere with place navigation (darkness, cholinergic blockade) but leave PC activity unaffected ...

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.

Frontiers in Computational Neuroscience, 2023 Recent experimental observations have shown that the reactivation of hippocampal place cells (PC) during sleep or wakeful immobility depicts trajectories that can go around barriers and can flexibly adapt to a changing maze layout.

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.

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

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 ...

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 ...
