  The sciences of natural and artificial intelligence are fundamentally
connected. Brain-inspired human-engineered AI are now the standard for
predicting human brain responses during vision, and conversely, the brain
continues to inspire invention in AI. To promote even deeper connections
between these fields, we here release the 2021 edition of the Algonauts Project
Challenge: How the Human Brain Makes Sense of a World in Motion
(http://algonauts.csail.mit.edu/). We provide whole-brain fMRI responses
recorded while 10 human participants viewed a rich set of over 1,000 short
video clips depicting everyday events. The goal of the challenge is to
accurately predict brain responses to these video clips. The format of our
challenge ensures rapid development, makes results directly comparable and
transparent, and is open to all. In this way it facilitates interdisciplinary
collaboration towards a common goal of understanding visual intelligence. The
2021 Algonauts Project is conducted in collaboration with the Cognitive
Computational Neuroscience (CCN) conference.
