Restoring the Multiple Sclerosis Associated Imbalance of Gut Indole Metabolites Promotes Remyelination and Suppresses Neuroinflammation

The paper shows that indole lactate (ILA), reduced in MS, restores gut microbiome metabolic balance, promoting remyelination and reducing neuroinflammation.

A Hierarchical Anti-Hebbian Network Model for the Formation of Spatial Cells in Three-Dimensional Space

This paper presents a hierarchical anti-Hebbian network model that simulates the formation of 3D spatial cells, including new cell types and explains anisotropic coding and discrepancies in 3D navigation.

A computational model that explores the effect of environmental geometries on grid cell representations

This paper introduces a computational model to study how environmental geometry affects grid cell periodicity, showing grid cells encode both local and global environmental information.

AN OSCILLATORY NETWORK MODEL OF HEAD DIRECTION, SPATIALLY PERIODIC CELLS AND PLACE CELLS USING LOCOMOTOR INPUTS

The paper presents two computational models that generate spatial cell responses like head direction, grid, border, and place cells without requiring symmetry assumptions, using locomotor inputs.
