If you have read the well-known book, "On Intelligence", you would agree with me that our brain is actually not a unique brain. Indeed, it is a collection of about 100,000 (one hundred thousand) mini brain. Or 100,000 mini columns as named by the author of the book. What does that mean? Our brain is a result of several levels of evolution. The first level is a part of the brain that controls basic needs such as breathe and eye movement. Sometimes we call this part the white matter. On top of the white matter, we have the so-called "gray matter", or neocortex. With neocortex, we can volunteerily control many muscles like walking and dancing. In AI, once we talk about human brain then that usually mean the neocortex. The neocortex is a thin layer, maybe about one inch. It is divided as mini-columns. There are about 100,000 mini-columns that are interconnected. Each mini column has millions of neurons (aka nerve cells in brain) and plays a role as a sub-brain. We hypot...
