The Thousand Brains Theory Explained
In this segment, Hawkins introduces the key ideas of his book, 'A Thousand Brains.' He explains that the neocortex consists of numerous independent modeling systems, each contributing to our understanding of the world. This theory challenges traditional views of intelligence by suggesting that our knowledge is distributed across many 'brains' within our own brain.
"and so um so that's where we start i got into this field because i just was curious as to who i am you know how you know how do i think what's going on in my head when i'm what i'm thinking what does ..."
The Voting Mechanism of the Brain
Hawkins describes how different modeling systems in the brain communicate and reach consensus through a voting mechanism. He explains that while we perceive ourselves as having a singular experience, our brains are actually processing multiple inputs and models simultaneously, leading to a unified perception of reality.
