Grid cells, border cells, and discrete complex analysis [PDF]
Frontiers in Computational Neuroscience, 2023 We propose a mechanism enabling the appearance of border cells—neurons firing at the boundaries of the navigated enclosures. The approach is based on the recent discovery of discrete complex analysis on a triangular lattice, which allows constructing ...

A memory model of rodent spatial navigation in which place cells are memories arranged in a grid and grid cells are non-spatial [PDF]
eLifeA theory and neurocomputational model are presented that explain grid cell responses as the byproduct of equally dissimilar hippocampal memories. On this account, place and grid cells are best understood as the natural consequence of memory encoding and ...
