IBL Behavioral Data on AWS

Electrophysiological recordings acquired using Neuropixels probes in different mice and labs, targeting the same brain locations (including posterior parietal cortex, hippocampus, and thalamus).

Electrophysiological recordings of mouse brain activity acquired during a decision making task in multiple autism mice models.

BrainWideBench is a large-scale, multi-task benchmark for evaluating neural foundation models, derived from the International Brain Laboratory (IBL) Brainwide Map dataset. It contains preprocessed Neuropixels recordings from 139 mice spanning 276 brain regions during a standardized visual decision-making task. The benchmark is organized around three complementary task suites: behavioral decoding (TS1), neural activity prediction (TS2), and brain region identification (TS3). Data are processed into a standardized format using the torch_brain library and include spike-sorted neural recordings, behavioral signals (wheel movements, paw kinematics, whisker motion energy, lick detection), trial structure, stimulus parameters, and anatomical annotations. A strict animal-level train/evaluation split separates 126 pretraining animals (423 sessions) from 13 held-out evaluation animals (29 sessions), enabling reproducible evaluation of across-animal generalization.
