The memory of the sense of one’s body becomes so ingrained in the neural circuits governing self-experience that the brain has difficulty reorganizing itself after a crippling accident or stroke. If painful enough, the person may not be able to accept the truth. A false belief can be constructed, triggering an emotional memory that feels utterly present and real (e.g., man with phantom erections after penis removal; person ‘sees’ fat on their body where there is none in anorexia nervosa). fMRI scans showed that the sensory motor areas of the body do not distinguish between imaginary and actual images and activities. Human beings have a great capacity for sticking to false beliefs with great passion and tenacity. According to Dr Bruce Lipton, even-rational scientists are not immune.
