Actionable neural representations: Grid cells from minimal constraints

W Dorrell, PE Latham, TEJ Behrens… - arXiv preprint arXiv …, 2022 - arxiv.org
To afford flexible behaviour, the brain must build internal representations that mirror the
structure of variables in the external world. For example, 2D space obeys rules: the same set …

Medial entorhinal cortex mediates learning of context-dependent interval timing behavior

ER Bigus, HW Lee, JC Bowler, J Shi, JG Heys - Nature Neuroscience, 2024 - nature.com
Episodic memory requires encoding the temporal structure of experience and relies on brain
circuits in the medial temporal lobe, including the medial entorhinal cortex (MEC). Recent …

A recurrent neural circuit mechanism of temporal-scaling equivariant representation

J Zuo, X Liu, YN Wu, S Wu… - Advances in Neural …, 2023 - proceedings.neurips.cc
Time perception is critical in our daily life. An important feature of time perception is temporal
scaling (TS): the ability to generate temporal sequences (eg, motor actions) at different …

[HTML][HTML] A neurocomputational model of goal-directed navigation in insect-inspired artificial agents
