A neural-level model of spatial memory and imagery by Andrej Bicanski, Neil Burgess

“…Simulated behavior and firing rate maps are compared to experimental data, for example showing how object-vector cells allow items to be remembered within a contextual representation based on environmental boundaries, and how grid cells could update the viewpoint in imagery during planning and short-cutting by driving sequential place cell activity.…”

Hippocampal remapping is constrained by sparseness rather than capacity. by Axel Kammerer, Christian Leibold

“…Potential candidates to read out the space information of this grid code and to combine it with other sensory cues are hippocampal place cells. In this paper, we investigate a population of grid cells providing feed-forward input to place cells. …”

A computational predictor of human episodic memory based on a theta phase precession network. by Naoyuki Sato, Yoko Yamaguchi

“…In the rodent hippocampus, a phase precession phenomena of place cell firing with the local field potential (LFP) theta is called "theta phase precession" and is considered to contribute to memory formation with spike time dependent plasticity (STDP). …”

Cortical reactivation of spatial and non-spatial features coordinates with hippocampus to form a memory dialogue by HaoRan Chang, Ingrid M. Esteves, Adam R. Neumann, Majid H. Mohajerani, Bruce L. McNaughton

“…A recent study has shown that the secondary motor cortex carries two types of representations: place cell-like activity, which were impaired by hippocampal lesions, and responses tied to visuo-tactile cues, which became more pronounced following hippocampal lesions. …”

Memory consolidation from seconds to weeks: A three-stage neural network model with autonomous reinstatement dynamics by Florian eFiebig, Florian eFiebig, Anders eLansner, Anders eLansner

“…Spontaneous reactivations of hippocampal memories, as observed in place cell reactivations during slow-wave-sleep, are supposed to drive neocortical reinstatements and facilitate this process.…”

A neural code for time and space in the human brain by Daniel R. Schonhaut, Zahra M. Aghajan, Michael J. Kahana, Itzhak Fried

“…The prevalence, firing rates, and behavioral coding strengths of time cells and place cells are indistinguishable—yet time cells selectively remap between search and retrieval tasks, while place cell responses remain stable. …”
