Relevance of UMAP for efficient and robust spike sorting

This paper demonstrates that using UMAP improves spike sorting performance, efficiency, and robustness in both synthetic and experimental data.

Thalamocortical interactions shape hierarchical neural variability during stimulus perception

This study examines how thalamocortical interactions shape neural variability during stimulus perception in monkeys, revealing distinct dynamics across brain regions.

Hierarchical unimodal processing within the primary somatosensory cortex during a bimodal detection task

The paper investigates whether neurons in the primary somatosensory cortex encode tactile and acoustic stimuli during a bimodal detection task, finding they are unimodal and functionally distinct.

An abstract categorical decision code in dorsal premotor cortex

This study identifies a categorical decision signal in dorsal premotor cortex (DPC) during a vibrotactile categorization task, showing sustained activity across task phases and consistent responses across stimulus attributes.
