Your body is constantly generating new cells. In your digestive tract, the colon’s lining turns over every five to seven days. Your red blood cells replace themselves every few weeks, skin cells about once a month. But certain organs are a big exception. Contrary to popular belief, we are not biological Theseus’ ships, reconstructing ourselves entirely from fresh building blocks every seven years. Most of your neurons, the cells that fast-track information across the brain, spine, and sensory organs, have the same lifespan as you do.

Funny that they used an artificial brain to study the real brain.
Seems like not everyone agrees, just yet.
