These sort of studies always remind me of an issue in consciousness research called the binding problem. You experience a single stream of consciousness, one in which everything, your percepts and sensations and emotions, are bound together, and the “problem” is that we don’t know how this works. It’s difficult to figure out because this binding is fractal, all the way down; you don’t experience colors and shapes separately, you experience a colored shape. But how do the contents get affixed together in consciousness in all the complex ways they’re supposed to? Via what rule does it work? One popular answer in the neuroscientific literature is that binding occurs via a process best described as “information transmission plus synchronization.” Neurons fire at a particular frequency in one region of the brain, which then synchronize with another region’s firing. In other words, parts of the brain dance.
