In a Japanese lab in the mid-90s, researchers taught macaque monkeys a party trick: use a rake to pull food that was just out of reach.
It looks like a cute circus move. But the researchers weren't watching the monkey. They were watching its brain.
They recorded activity in neurons that track "me" versus "not me"—the space around your hand where you can grab, touch, act.

At first, those neurons fired for objects near the monkey's hand.
Then the monkey got good. Some neurons started responding as if the tip of the rake was the hand. The brain didn't just control the tool—it absorbed it into the body map.
Your tools become part of your identity. Ownership is something your nervous system learns by doing, and the fastest route to feeling capable is holding something you made.
