The body is connected to itself. And although all of the cells that make up our body are distinct from each other, when our consciousness comes into play, all of the parts cooperate.
This gives rise to another way to think about the brain. On a micro scale, all of the body’s cells, all of its parts, are interconnected. The big toe is actually part of the brain. The toe supports our balance, which allows mobility, and in this way the big toe allows our brain to get around.
Every one of our body’s structures serve the brain in one way or another.
Stepping out from this, we are group animals, each with an individual brain, which in attachment mode serves to support other individual brains.
On a macro scale, when we step further out we can view our society as an integrated brain system.
