Vilayanur Ramachandran talks about what brain damage reveals about the connection between celebral tissue and the mind. In a nutshell: a localized brain injury in the pathway between the fusiform gyrus (face recognition module) and amygdala (emotional processing) can cause people to experience the delusion that someone they recognize is an imposter. Amputees whose limbs were paralyzed before amputation end up with paralyzed phantom limbs; visual feedback using a mirror box cures the "paralysis". Synaesthesia gives deep insights into creativity.
