Adult neurogenesis and the dentate gyrus: predicting function from form

KM Christian, G Ming, H Song - Behavioural brain research, 2020 - Elsevier
Hypotheses about the functional properties of the dentate gyrus and adult dentate
neurogenesis have been shaped by early observations of the anatomy of this region, mostly …

Pattern separation of spiketrains in hippocampal neurons

AD Madar, LA Ewell, MV Jones - Scientific Reports, 2019 - nature.com
Pattern separation is a process that minimizes overlap between patterns of neuronal activity
representing similar experiences. Theoretical work suggests that the dentate gyrus (DG) …

Pattern separation in the hippocampus through the eyes of computational modeling

S Chavlis, P Poirazi - Synapse, 2017 - Wiley Online Library
Pattern separation is a mnemonic process that has been extensively studied over the years.
It entails the ability‐of primarily hippocampal circuits‐to distinguish between highly similar …

Disparate forms of heterogeneities and interactions among them drive channel decorrelation in the dentate gyrus: Degeneracy and dominance

P Mishra, R Narayanan - Hippocampus, 2019 - Wiley Online Library
The ability of a neuronal population to effectuate channel decorrelation, which is one form of
response decorrelation, has been identified as an essential prelude to efficient neural …

Deficits in behavioral and neuronal pattern separation in temporal lobe epilepsy

AD Madar, JA Pfammatter, J Bordenave… - Journal of …, 2021 - Soc Neuroscience
In temporal lobe epilepsy, the ability of the dentate gyrus to limit excitatory cortical input to
the hippocampus breaks down, leading to seizures. The dentate gyrus is also thought to …

Quantitative properties of a feedback circuit predict frequency-dependent pattern separation

O Braganza, D Mueller-Komorowska, T Kelly, H Beck - Elife, 2020 - elifesciences.org
Feedback inhibitory motifs are thought to be important for pattern separation across species.
How feedback circuits may implement pattern separation of biologically plausible …

Sparse modern hopfield networks

A Martins, V Niculae, DC McNamee - Associative Memory {\&} …, 2023 - openreview.net
Ramsauer et al.(2021) recently pointed out a connection between modern Hopfield
