Slow synaptic plasticity from the hippocampus underlies gradual mapping and fragmentation of novel spaces by grid cells

The paper shows that slow hippocampus-to-entorhinal plasticity underlies gradual grid cell map formation and fragmentation in novel environments through longitudinal imaging and modeling.

A theory and recipe to construct general and biologically plausible integrating continuous attractor neural networks

This paper introduces a framework to construct biologically plausible continuous attractor neural networks with specified topologies and integration capabilities.

Episodic and associative memory from spatial scaffolds in the hippocampus

This paper introduces a neural network model of the hippocampus that integrates spatial and episodic memory by using structured scaffold states for high-capacity, error-correcting memory storage.

Developmental synaptic pruning sharpens neural representations for predictive motor control

This study shows that synaptic pruning in zebrafish cerebellum sharpens neural representations and improves predictive motor control by reducing convergence of differently tuned inputs.

Propofol anesthesia destabilizes neural dynamics across cortex

This study uses DeLASE to show that propofol anesthesia reduces dynamic stability in macaque cortex, mirroring destabilized linear systems.

Self-organized emergence of modularity, hierarchy, and mirror reversals from competitive synaptic growth in a developmental model of the visual pathway

This paper demonstrates that a simple synaptic growth rule generates modular, hierarchical, and topographically organized visual pathways in a developmental model.

Emergence of robust global modules from local interactions and smooth gradients

This paper introduces peak selection, a process that explains how local interactions and smooth gradients can lead to robust global modular organization in biological systems.
