The content of hippocampal “replay”

BE Pfeiffer - Hippocampus, 2020 - Wiley Online Library
One of the most striking features of the hippocampal network is its ability to self‐generate
neuronal sequences representing temporally compressed, spatially coherent paths. These …

Brain-inspired replay for continual learning with artificial neural networks

GM Van de Ven, HT Siegelmann, AS Tolias - Nature communications, 2020 - nature.com
Artificial neural networks suffer from catastrophic forgetting. Unlike humans, when these
networks are trained on something new, they rapidly forget what was learned before. In the …

Is hippocampal remapping the physiological basis for context?

JL Kubie, ERJ Levy, AA Fenton - Hippocampus, 2020 - Wiley Online Library
Abstract In 1980, Nadel and Wilner extended Richard Hirsh's notion that the hippocampus
creates environmental representations, called “contexts,” suggesting that the fundamental …

Constant sub-second cycling between representations of possible futures in the hippocampus

K Kay, JE Chung, M Sosa, JS Schor, MP Karlsson… - Cell, 2020 - cell.com
Cognitive faculties such as imagination, planning, and decision-making entail the ability to
represent hypothetical experience. Crucially, animal behavior in natural settings implies that …

Spatiotemporal patterns of neocortical activity around hippocampal sharp-wave ripples

J Karimi Abadchi, M Nazari-Ahangarkolaee, S Gattas… - elife, 2020 - elifesciences.org
A prevalent model is that sharp-wave ripples (SWR) arise 'spontaneously'in CA3 and
propagate recent memory traces outward to the neocortex to facilitate memory consolidation …

Lifelong generative modeling

J Ramapuram, M Gregorova, A Kalousis - Neurocomputing, 2020 - Elsevier
Lifelong learning is the problem of learning multiple consecutive tasks in a sequential
manner, where knowledge gained from previous tasks is retained and used to aid future …

Inhibitory parvalbumin basket cell activity is selectively reduced during hippocampal sharp wave ripples in a mouse model of familial Alzheimer's disease

A Caccavano, PL Bozzelli, PA Forcelli… - Journal of …, 2020 - Soc Neuroscience
Memory disruption in mild cognitive impairment (MCI) and Alzheimer9s disease (AD) is
poorly understood, particularly at early stages preceding neurodegeneration. In mouse …
