Hippocampal remapping as hidden state inference
eLife, 2020 Cells in the hippocampus tuned to spatial location (place cells) typically change their tuning when an animal changes context, a phenomenon known as remapping. A fundamental challenge to understanding remapping is the fact that what counts as a ‘‘context

To remap or not remap: Experience matters [PDF]
Cell ReportsRemapping is a fundamental feature of hippocampal contextual representations that underlies memory encoding and separation. Recently in Cell Reports, Tarcsay et al1 have shown that experience determines remapping dynamics in context learning.

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 ...

Hippocampal Remapping and Its Entorhinal Origin
Frontiers in Behavioral Neuroscience, 2018 The activity of hippocampal cell ensembles is an accurate predictor of the position of an animal in its surrounding space. One key property of hippocampal cell ensembles is their ability to change in response to alterations in the surrounding environment,

Cell ReportsSummary: The nature and function of perisaccadic receptive field (RF) remapping have been controversial. We use a delayed saccade task to reduce previous confounds and examine the remapping time course in the lateral intraparietal area and frontal eye ...

Modeling flexible behavior with remapping-based hippocampal sequence learning [PDF]
eLifeAnimals flexibly change their behavior depending on context. It is reported that the hippocampus is one of the most prominent regions for contextual behaviors, and its sequential activity shows context dependency.

Attention Trade-Off for Localization and Saccadic Remapping
Vision, 2021 Predictive remapping may be the principal mechanism of maintaining visual stability, and attention is crucial for this process. We aimed to investigate the role of attention in predictive remapping in a dual task paradigm with two conditions, with and ...

Hippocampal place cell remapping occurs with memory storage of aversive experiences
eLife, 2023 Aversive stimuli can cause hippocampal place cells to remap their firing fields, but it is not known whether remapping plays a role in storing memories of aversive experiences. Here, we addressed this question by performing in vivo calcium imaging of CA1
