Here, we review the basis of contextual memory at a conceptual and cellular level. We begin with an overview of the philosophical foundations of traversing space, followed by theories covering the material bases of contextual representations in the h

The hippocampus is a brain region critically involved in memory. In this study, the authors demonstrate that reactivating hippocampal neurons associated with positive memories can disrupt a fear response in mice.

The hippocampus contains neurons that correspond to two partially non-overlapping sets of positive and negative engrams, which may be distinguished by molecular, cellular, and projection-specific features.

The dentate gyrus (DG) engages in sustained Arc transcription for at least 8 hours following behavioral induction, and this time course may be functionally coupled to the unique role of the DG in hippocampus-dependent learning and memory. The factors

In mammals, episodic memory and spatial cognition involve context-specific recruitment of unique ensembles in the hippocampal formation (HF). Despite their capacity for sophisticated spatial (e.g., for migration) and episodic-like (e.g., for food-cac

Memories are stored in the brain as cellular ensembles activated during learning and reactivated during retrieval. Using the Tet-tag system, we labeled dorsal dentate gyrus (dDG) neurons activated by positive, neutral or negative experiences with cha

Contextual information is represented in the hippocampus (HPC) partially through the recruitment of distinct neuronal ensembles. It is believed that reactivation of these ensembles underlies memory retrieval processes. Recently, we showed that norepi

The hippocampus is involved in processing a variety of mnemonic computations specifically the spatiotemporal components and emotional dimensions of contextual memory.1–3 Recent studies have demonstrated vast structural and functional heterogeneity
