In 1954, two researchers at Canada's McGill University by chance found how people be taught to repeat habits that is useful to our survival. An electrode implanted in the Alpha Brain Cognitive Support of a rat had slipped from its intended place and had come to relaxation on the medial forebrain bundle, a gaggle of nerve cells that leads from deep within the Alpha Brain Cognitive Support to the prefrontal cortex. Upon delivering a collection of electrical shocks to the electrode, the rat displayed a keen curiosity in the world of its field it had been exploring when it acquired the primary jolt. Upon additional investigation, Olds and Milner realized that what they'd discovered was the mind's reward heart, a system of areas related to delivering a way of pleasure in return for certain behaviors like eating and mating. This discovery was revolutionary
