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.

A Brain-Wide Map of Neural Activity during Complex Behaviour

The paper presents a brain-wide neural activity map from 621,733 neurons across 139 mice performing a decision-making task, showing how neural activity encodes task variables across brain regions.

Data architecture for a large-scale neuroscience collaboration

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

Mice alternate between discrete strategies during perceptual decision-making

The paper shows mice switch between multiple decision-making strategies during perceptual tasks, challenging the assumption of a single strategy.

Extracting the Dynamics of Behavior in Decision-Making Experiments

This paper introduces a method to analyze time-varying decision-making strategies in animals and applies it to data from mice, rats, and humans.

A comparison of deep learning and linear-nonlinear cascade approaches to neural encoding

The paper compares deep learning and traditional methods for fitting linear-nonlinear-Poisson models of neural encoding, finding that deep learning methods achieve higher accuracy and require more filters.
