@Tfmonkey Technically all nerve tissue is a form of brain tissue, they are mechanistically identical. If someone loses a limb they are losing a portion of their brain. Once one see's the brain not as a singular organ thats plugged into the spinal cord, but rather as a central core of an otherwise decentralized system of thinking, it changes ones perspective of biophysics. Biology is an absolutely fascinating subject that I hold immense reverence for even though its outside my domain expertise.
