The Algonauts Project
Below you will find links to all editions of The Algonauts Project.
The 2025 edition focuses on explaining responses in the human brain as participants perceive complex multimodal movies. Through collaboration with the Courtois Project on Neuronal Modelling (CNeuroMod), the challenge runs on the largest human brain dataset available, opening new venues for accurate models of neural responses to multimodal naturalistic stimulation. To promote more robust models of the brain, the 2025 challenge features a selection process based on out-of-distribution generalization. The challenge is organized in partnership with the Conference on Cognitive Computational Neuroscience (CCN).
The 2023 edition focuses on explaining responses in the human brain as participants perceive complex natural visual scenes. Through collaboration with the Natural Scenes Dataset (NSD) team, this challenge runs on the largest suitable brain dataset available, opening new venues for data-hungry modeling. The challenge is organized in partnership with the Conference on Cognitive Computational Neuroscience (CCN)
The 2021 edition was centered around video perception and event understanding. The challenge focused on explaining responses in the human brain as subjects watched short video clips of everyday events.
The first edition focused on explaining brain responses as human subjects studied still images of everyday objects.
