Summary of Loretta Graziano Breuning's Habits of a Happy Brain

Please note: This is a companion version & not the original book. Sample Book Insights: #1 Your brain is focused on survival, and it is not easy being a survivor. You have inherited a brain that is focused on survival, and it is not easy being a survivor. #2 The four happy chemicals are dopamine, endorphin, oxytocin, and serotonin. They are triggered when your brain sees something that is good for your survival, and they turn off when something bad crosses your path. #3 The human brain has a limbic system, which is made up of the hippocampus, amygdala, pituitary, hypothalamus, and other parts. The human brain is surrounded by a huge cortex. Your cortex and limbic system are always working together to keep you alive. #4 Your inner mammal rewards you with good feelings when you do something good for your survival. Each of the happy chemicals motivates a different type of survival behavior: dopamine motivates you to get what you need, even if it takes a lot of effort, endorphin motivates you to ignore pain, and so on.
