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