The Binding Problem
The puzzle of how a brain made of separate, parallel, distributed systems—processing color in one region, motion in another, shape in a third—produces a single unified experience, and why the AI architectures engineered to solve its functional half leave its phenomenal half exactly where Crick left it.
You see one red ball, moving, here. The brain that sees it is processing color in V4, motion in MT, shape in the ventral stream, location in the dorsal stream—distributed computations that are nowhere co-located. Yet what you experience is not a loose collection of color-data and motion-data and shape-data. It is one thing, now, here. How the brain binds its scattered computations into the unity of a single perceived object is the binding problem, and
Francis Crick took it seriously as perhaps the central obstacle to a neural theory of consciousness. His proposal, with Christof Koch, was that neurons representing features of the same object might fire together in synchronized rhythmic lockstep—that temporal coherence might be the physical signature of a bound, conscious percept. The parallel to modern AI is precise and instructive. A transformer is a massively parallel system whose representation of any input is distributed
