A time-causal and time-recursive scale-covariant scale-space representation of temporal signals and past time

T Lindeberg - Biological Cybernetics, 2023 - Springer
This article presents an overview of a theory for performing temporal smoothing on temporal
signals in such a way that:(i) temporally smoothed signals at coarser temporal scales are …

A temporal record of the past with a spectrum of time constants in the monkey entorhinal cortex

IM Bright, MLR Meister, NA Cruzado… - Proceedings of the …, 2020 - National Acad Sciences
Episodic memory is believed to be intimately related to our experience of the passage of

[HTML][HTML] Foundations of a temporal RL

MW Howard, ZG Esfahani, B Le, PB Sederberg - ArXiv, 2023 - ncbi.nlm.nih.gov
Recent advances in neuroscience and psychology show that the brain has access to

Neural population dynamics underlying evidence accumulation in multiple rat brain regions

B DePasquale, CD Brody, JW Pillow - Elife, 2024 - elifesciences.org

Cognitive computation using neural representations of time and space in the Laplace domain

MW Howard, ME Hasselmo - arXiv preprint arXiv:2003.11668, 2020 - arxiv.org
Memory for the past makes use of a record of what happened when---a function over past
time. Time cells in the hippocampus and temporal context cells in the entorhinal cortex both …

A neural cognitive architecture

CR Huyck - Cognitive Systems Research, 2020 - Elsevier
It is difficult to study the mind, but cognitive architectures are one tool. As the mind emerges
from the behaviour of the brain, neuropsychological methods are another method to study …
