Chen X, Cheng N, Wang C, Knierim J
Proc Natl Acad Sci U S A
. 2025 Jan;
122(5):e2416214122.
PMID: 39883841
The hippocampal dentate gyrus (DG) is thought to orthogonalize inputs from the entorhinal cortex (pattern separation) and relay this information to the CA3 region. In turn, attractor dynamics in CA3...

Nat Commun
. 2024 Dec;
15(1):10630.
PMID: 39638805
Vector coding is a major mechanism by which neural systems represent an animal's location in both global and local, item-based reference frames. Landmark vector cells (LVCs) in the hippocampus complement...

Wang C, Lee H, Rao G, Knierim J
Nat Commun
. 2024 Dec;
15(1):10533.
PMID: 39627238
Episodic memory involves the processing of spatial and temporal aspects of personal experiences. The lateral entorhinal cortex (LEC) plays an essential role in subserving memory. However, the mechanisms by which...

Madhav M, Jayakumar R, Li B, Lashkari S, Wright K, Savelli F, et al.
Nat Neurosci
. 2024 Jun;
27(8):1599-1608.
PMID: 38937582
Hippocampal place cells are influenced by both self-motion (idiothetic) signals and external sensory landmarks as an animal navigates its environment. To continuously update a position signal on an internal 'cognitive...

. 2024 May;
PMID: 38699376
Representations of continuous variables are crucial to create internal models of the external world. A prevailing model of how the brain maintains these representations is given by continuous bump attractor...

Hippocampus
. 2023 Dec;
34(2):88-99.
PMID: 38073523
The hippocampal formation is vulnerable to the process of normal aging. In humans, the extent of this age-related deterioration varies among individuals. Long-Evans rats replicate these individual differences as they...

Nat Rev Neurosci
. 2023 Jun;
24(8):502-517.
PMID: 37316588
There has been considerable speculation regarding the function of the dentate gyrus (DG) - a subregion of the mammalian hippocampus - in learning and memory. In this Perspective article, we...

Cell Rep
. 2023 Apr;
42(4):112334.
PMID: 37043350
Hippocampal place cells exhibit spatially modulated firing, or place fields, which can remap to encode changes in the environment or other variables. Unique among hippocampal subregions, the dentate gyrus (DG)...
