Grella S, Donaldson T
Front Mol Neurosci
. 2024 Feb;
17:1342622.
PMID: 38375501
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...

Commun Biol
. 2022 Sep;
5(1):1009.
PMID: 36163262
The hippocampus is involved in processing a variety of mnemonic computations specifically the spatiotemporal components and emotional dimensions of contextual memory. Recent studies have demonstrated cellular heterogeneity along the hippocampal...

Nat Commun
. 2022 Sep;
13(1):4733.
PMID: 36096993
Memories are stored in the brain as cellular ensembles activated during learning and reactivated during retrieval. Using the Tet-tag system in mice, we label dorsal dentate gyrus neurons activated by...

Neuropsychopharmacology
. 2022 Aug;
47(11):1992-2001.
PMID: 35941286
The formation and extinction of fear memories represent two forms of learning that each engage the hippocampus and amygdala. How cell populations in these areas contribute to fear relapse, however,...

Grella S, Gomes S, Lackie R, Renda B, Marrone D
Behav Pharmacol
. 2021 Aug;
32(7):531-548.
PMID: 34417358
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...

Doucette E, Merfeld E, Leblanc H, Monasterio A, Cincotta C, Grella S, et al.
Neurobiol Learn Mem
. 2020 Nov;
176:107321.
PMID: 33164892
The hippocampus processes both spatial-temporal information and emotionally salient experiences. To test the functional properties of discrete sets of cells in the dorsal dentate gyrus (dDG), we examined whether chronic...

Hippocampus
. 2020 Sep;
31(1):3-10.
PMID: 32946184
Alcohol withdrawal directly impacts the brain's stress and memory systems, which may underlie individual susceptibility to persistent drug and alcohol-seeking behaviors. Numerous studies demonstrate that forced alcohol abstinence, which may...

Learn Mem
. 2020 Mar;
27(4):150-163.
PMID: 32179657
Systems consolidation (SC) theory proposes that recent, contextually rich memories are stored in the hippocampus (HPC). As these memories become remote, they are believed to rely more heavily on cortical...

Curr Biol
. 2019 May;
29(11):1885-1894.e4.
PMID: 31130452
Emerging evidence indicates that distinct hippocampal domains differentially drive cognition and emotion [1, 2]; dorsal regions encode spatial, temporal, and contextual information [3-5], whereas ventral regions regulate stress responses [6],...

J Neurosci
. 2018 Nov;
39(3):445-455.
PMID: 30478033
Locus coeruleus (LC) neurons, the source of hippocampal norepinephrine (NE), are activated by novelty and changes in environmental contingencies. Based on the role of monoamines in reconfiguring invertebrate networks, and...
