Proc Natl Acad Sci U S A
. 2025 Mar;
122(11):e2417025122.
PMID: 40063792
A key feature of biological and artificial neural networks is the progressive refinement of their neural representations with experience. In neuroscience, this fact has inspired several recent studies in sensory...

. 2024 May;
43(6):114276.
PMID: 38814781
How the coordination of neuronal spiking and brain rhythms between hippocampal subregions supports memory function remains elusive. We studied the interregional coordination of CA3 neuronal spiking with CA1 theta oscillations...

Hippocampal cholecystokinin-expressing interneurons regulate temporal coding and contextual learning
Rangel Guerrero D, Balueva K, Barayeu U, Baracskay P, Gridchyn I, Nardin M, et al.
Neuron
. 2024 Apr;
112(12):2045-2061.e10.
PMID: 38636524
Cholecystokinin-expressing interneurons (CCKIs) are hypothesized to shape pyramidal cell-firing patterns and regulate network oscillations and related network state transitions. To directly probe their role in the CA1 region, we silenced...

J Neurosci
. 2023 Sep;
43(48):8140-8156.
PMID: 37758476
Although much is known about how single neurons in the hippocampus represent an animal's position, how circuit interactions contribute to spatial coding is less well understood. Using a novel statistical...

Cell Rep
. 2023 Aug;
42(9):113015.
PMID: 37632747
The execution of cognitive functions requires coordinated circuit activity across different brain areas that involves the associated firing of neuronal assemblies. Here, we tested the circuit mechanism behind assembly interactions...

Nat Commun
. 2022 Aug;
13(1):4826.
PMID: 35974109
The mammalian hippocampal formation (HF) plays a key role in several higher brain functions, such as spatial coding, learning and memory. Its simple circuit architecture is often viewed as a...

PMID: 33016875
In vitro work revealed that excitatory synaptic inputs to hippocampal inhibitory interneurons could undergo Hebbian, associative, or non-associative plasticity. Both behavioral and learning-dependent reorganization of these connections has also been...

Neuron
. 2020 Feb;
106(2):291-300.e6.
PMID: 32070475
Memory consolidation is thought to depend on the reactivation of waking hippocampal firing patterns during sleep. Following goal learning, the reactivation of place cell firing can represent goals and predicts...

Neuron
. 2020 Feb;
106(1):154-165.e6.
PMID: 32032512
Temporally organized reactivation of experiences during awake immobility periods is thought to underlie cognitive processes like planning and evaluation. While replay of trajectories is well established for the hippocampus, it...

. 2019 Mar;
363(6434):1443-1447.
PMID: 30923221
Grid cells with their rigid hexagonal firing fields are thought to provide an invariant metric to the hippocampal cognitive map, yet environmental geometrical features have recently been shown to distort...
