In fact, “stream” isn’t really the right word here, because it suggests some pooling of information within that stream, and that doesn’t happen in neurons. Instead, each nerve signal remains locked into an individual nerve. So, rather than a stream, you should think of the information traveling through the brain as sequences of blip blip blip blip … signals passing along individual strands of an immense tangle of billions of neurons. The binding problem is the problem of understanding how all the disparate blip-encoded information generates the unified perception of a bison.
