Monty Python’s Mr Gumby was anatomically on the money when he exclaimed “my brain hurts”. Our brains and bodies communicate via long axons that run from gray matter through our spinal cords. Neural communication is two way – when we cut a finger or knock a shin messages charge across a network of nerves to reach our brains, and it’s from here that feelings of physical hurt emanate. Communicating bodily damage is just one type of bi-directional traffic flowing between our brains and spinal cords; this network’s vital importance becomes devastating obvious when it fails.
