Attractor and integrator networks in the brain

M Khona, IR Fiete - Nature Reviews Neuroscience, 2022 - nature.com
In this Review, we describe the singular success of attractor neural network models in
describing how the brain maintains persistent activity states for working memory, corrects …

A unifying perspective on neural manifolds and circuits for cognition

C Langdon, M Genkin, TA Engel - Nature Reviews Neuroscience, 2023 - nature.com

[HTML][HTML] A framework for intelligence and cortical function based on grid cells in the neocortex

J Hawkins, M Lewis, M Klukas, S Purdy… - Frontiers in neural …, 2019 - frontiersin.org
How the neocortex works is a mystery. In this paper we propose a novel framework for
understanding its function. Grid cells are neurons in the entorhinal cortex that represent the …

Episodic memory: Neuronal codes for what, where, and when

J Sugar, MB Moser - Hippocampus, 2019 - Wiley Online Library
Episodic memory is defined as the ability to recall events in a spatiotemporal context.
Formation of such memories is critically dependent on the hippocampal formation and its …

A unified theory for the computational and mechanistic origins of grid cells

B Sorscher, GC Mel, SA Ocko, LM Giocomo, S Ganguli - Neuron, 2023 - cell.com
The discovery of entorhinal grid cells has generated considerable interest in how and why
hexagonal firing fields might emerge in a generic manner from neural circuits, and what their …
