Age-related changes in behavioural and neural variability in a decision-making task

This study examines age-related changes in neural and behavioural variability during a decision-making task in mice, finding increased neural variability and reduced variability quenching in specific brain regions.

Stiefel Manifold Dynamical Systems for Tracking Representational Drift

This paper introduces SMDS, a model that accounts for representational drift in neural data, outperforming LDS in log-likelihood and requiring fewer latent dimensions.

Reproducibility of in-vivo electrophysiological measurements in mice

This study evaluates the reproducibility of electrophysiological measurements across ten labs using standardized protocols and finds that variability in electrode targeting and statistical methods affects reproducibility.

Lightning Pose: improved animal pose estimation via semi-supervised learning, Bayesian ensembling, and cloud-native open-source tools

DARTsort: A modular drift tracking spike sorter for high-density multi-electrode probes

DARTsort improves spike sorting by incorporating drift tracking, outperforming Kilosort 2.5 on simulated data with drift and noise.

Three-dimensional spike localization and improved motion correction for Neuropixels recordings

This paper introduces methods for 3D spike localization and motion correction in Neuropixels recordings, improving spike sorting and neural activity tracking.
