Alpay: "Mashing the Pleasure Button": Mashing the Pleasure Button In humans, rats, and other mammals, the reward circuits is much more complex, as it is interwoven with brain centers involved in decision-making, planning, emotion, and memory storage. When we find an experience pleasurable, it sets in motion several processes with different time courses: (a) We like the experience (the immediate sensation of pleasure); (b) we associate both external seonsory cues (sights, sounds, odors, etc.) and internal cues (our own thoughts and feelings at the time) with the experience, and these associations allow us to predict how we should behave to repeat it; and (c) we assign a value to the pleasurable experience (from a little to a lot), so that in the future we can choose among several pleasurable experiences and determine how much effort we are willing to expend and risk we are willing to take in order to get them.
