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.

Mice infer stimulus-side priors from recent choices; prior signals are decodable pre-stimulus in 24.0% to 30.2% of 242 brain regions, including early visual and motor areas.

The SAFE Labs Handbook provides thirty commitments for improving lab culture, developed by group leaders and rated by researchers, showing high importance but low implementation rates.

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.

The paper introduces two public websites for exploring large-scale electrophysiology data from the International Brain Laboratory, enabling cross-platform access to behavioral trials and neuronal data.

The paper introduces an infinite hidden semi-Markov model to analyze learning curves in mice, finding three major learning stages and behavior changes after rest periods.

The paper describes a modular data architecture for a neuroscience collaboration, enabling data contribution, access, and analysis across multiple labs.

This study identifies a Vamp2 mutation in mice that causes sleep-wake transition deficits by reducing synaptic release probability.

This study shows that loss of Frrs1l in mice causes reduced synaptic AMPA receptor levels, leading to motor, cognitive, and electrographical abnormalities.
