Network dynamics underlying activity-timescale differences between cortical regions

The paper investigates how network dynamics differ between cortical regions with distinct activity timescales, showing that long-timescale areas sustain input over longer periods through specific neuronal recruitment patterns.

Cognitive processes are disentangled at cortex-wide scales

The paper shows that cognitive processes like evidence accumulation and memory are represented as near-orthogonal subspaces across the cortex, breaking down during errors.

Neuronal population activity dynamics reveal a low-dimensional signature of operant learning

The paper identifies a low-dimensional signature of operant learning through neuronal population activity dynamics in Aplysia feeding.

Unsupervised functional neurocartography of the Aplysia buccal ganglion

This study adapts a functional neurocartography framework to Aplysia buccal ganglia to improve neuron correspondence across subjects using unsupervised machine learning.
