There's an interesting theory running around Neuroscience (and, let me tell you what a Harvard educated neuroscientist said about virtually all neuroscience and brain studies: "they're great theories, they've got tiny experimental observations to back them up, they're basically pulling all of this out of their asses.") so, anyway, the theory goes that "thoughts" are encoded as repeating firing patterns. As far as I understand the theory and what little I read of OP, the patterns themselves are more nuanced than binary, but one "idea" might be encoded as firing pattern like ..-..- ..-..- while a competing idea might be encoded as a different firing pattern: ...---... ...---... so, there can be thousands of distinct firing patterns (continuing the morse code analogy, even a simple 3 letter code holds over 17000 unique patterns, make those inter-firing intervals analog and a virtual infinity of patterns can be encoded with 8 to 10 intervals) so, groups of neurons start "singing" their songs based on inputs from other areas of the brain/body, usually several different patterns based on competing inputs from different "source" areas. The neurons in a "processing node" sort of fight it out, each repeating their idea of the "right" firing pattern until they reach some form of consensus, then that coherent pattern becomes a "valid" input to the next level of processing, which itself may be getting inputs from a bunch of different areas that it has to hash out until it can reach a coherent pattern to pass along. Eventually, these "ideas" fire off motor control routines and actuate the body to move, speak, etc.
The thing that's most intriguing to me about this theory is that it's somewhat repeated in human society. We get together, repeat ideas among small groups, pass them along to "higher levels" and eventually act as societies to do things. Now, with the internet, we have billions of people acting in some ways like neurons in a brain, reaching consensus about some things and chanting in chaotic disagreement about others.
