Everything about us is an emergent property of our enormous, intricate, and orderly nervous system. And our nervous system, like any other system, requires security. Providing that security is the job of our immune system. But treason at the biological level is real. At every level of the nervous system there are internal miscreants, rabble-rousers, and spies. In this lecture, neurologist Dr. Roy Baskind will take us on a tour of those autoimmune domestic threats – from our nerves, up our spinal column, and into our brain – and in the process expose our internal ‘fifth column’: autoimmunity against our own nervous system. This lecture aims to leave us with a newfound awe of our personal neurological government and how it can all go so wrong.
