Quoted By:
Your body's cells reproduce and replace themselves regularly, but that doesn't apply to your brain and your entire nervous system, they are not made up of cells. I'm not joking or calling you stupid when I say you don't have any brain cells, it's just a fact, they aren't cells, they don't reproduce. There are organisms in your body that create your nervous system tissue, and they also repair it, but nervous system tissue (pic related) does not grow back, or reproduce on it's own.
The tiny creatures that live inside us, make our nerve tissue, they deserve some respect, and recognition. Stop abusing them.
