Methodological Caveats in the Detection of Coordinated Replay between Place Cells and Grid Cells
Frontiers in Systems Neuroscience, 2017 At rest, hippocampal “place cells,” neurons with receptive fields corresponding to specific spatial locations, reactivate in a manner that reflects recently traveled trajectories.

Micromachines, 2022 Simultaneous monitoring of animal behavior and neuronal activity in the brain enables us to examine the neural underpinnings of behaviors. Conventionally, the neural activity data are buffered, amplified, multiplexed, and then converted from analog to ...

Dorsal CA1 Hippocampal Place Cells Form a Multi-Scale Representation of Megaspace
bioRxiv, 2021 Spatially firing “place cells” within the hippocampal CA1 region form internal maps of the environment necessary for navigation and memory. In rodents, these neurons have been almost exclusively studied in small environments (

Macrophage morphological plasticity and migration is Rac signalling and MMP9 dependant
Scientific Reports, 2021 In vitro, depending on extracellular matrix (ECM) architecture, macrophages migrate either in amoeboid or mesenchymal mode; while the first is a general trait of leukocytes, the latter is associated with tissue remodelling via Matrix Metalloproteinases ...

Spatial cognition and the avian hippocampus: Research in domestic chicks
Frontiers in Psychology, 2022 In this review, we discuss the functional equivalence of the avian and mammalian hippocampus, based mostly on our own research in domestic chicks, which provide an important developmental model (most research on spatial cognition in other birds relies on

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 obviously ...

Hippocampus Maintains a Coherent Map Under Reward Feature–Landmark Cue Conflict
Frontiers in Neural Circuits, 2022 Animals predominantly use salient visual cues (landmarks) for efficient navigation. When the relative position of the visual cues is altered, the hippocampal population exhibits heterogeneous responses and constructs context-specific spatial maps ...

‘Fearful-place’ coding in the amygdala-hippocampal network
eLife, 2021 Animals seeking survival needs must be able to assess different locations of threats in their habitat. However, the neural integration of spatial and risk information essential for guiding goal-directed behavior remains poorly understood.

Rapid learning of predictive maps with STDP and theta phase precession
eLife, 2023 The predictive map hypothesis is a promising candidate principle for hippocampal function. A favoured formalisation of this hypothesis, called the successor representation, proposes that each place cell encodes the expected state occupancy of its target ...

Mechanisms for Cognitive Impairment in Epilepsy: Moving Beyond Seizures
Frontiers in Neurology, 2022 There has been a major emphasis on defining the role of seizures in the causation of cognitive impairments like memory deficits in epilepsy. Here we focus on an alternative hypothesis behind these deficits, emphasizing the mechanisms of information ...
