This is Hidden Brain. I'm Shankar Vedantam. It seems like the simplest choice in the world. Given the option between pain and pleasure, we ought to choose pleasure. Is it better to be hungry or full? Better to be tired or alert? Better to watch another episode of our favorite TV show or do the dishes? It isn't just our own minds that that tell us to choose the path of enjoyment and indulgence. Our friends remind us that life is short. Say no to dessert or another round of drinks and someone might call you a spoilsport. At Stanford University, psychiatrist Anna Lemke has heard the same messages. But as a scientist, she's also studied the way our brains balance pain and pleasure. The two sit on opposite ends of a neural seesaw and the brain constantly attempts to bring them into equilibrium, or what is known as homeostasis. When we press down hard and often on the pleasure side of the seesaw, triggering bursts of the neurotransmitter dopamine, Anna says the brain automatically compensates by pressing down on the other side, producing a dopamine deficit. Over time, as people press down too much or too often on the pleasure side of the equation, the brain compensates so forcefully that we start to walk around with a chronic dopamine deficit. This can manifest as anxiety, irritability and depression. There is complex neurochemistry behind the process of homeostasis, but ANA has come up with a simple way to visualize this. When you press down on one side of the seesaw, imagine a bunch of gremlins inside your head jumping on the other side of the seesaw. We explored how this mechanism works and why it exists in our previous episode. If you missed it, I strongly suggest you listen to it first. Today we continue with the second part of our story about the paradoxical effects of pleasure. And we ask what it means to live a life of balance and harmony. How to work with the brain rather than against it. This week on Hidden Brain. Support for Hidden Brain comes from viz. Struggling to see up close. Make it visible with viz.

She has worked with many patients who have addictions, not just to drugs like cocaine and heroin, but to everyday activities taken to excess. She has treated patients with a range of out of control indulgences, from eating and drinking to online shopping and sports betting. Around the time she turned 40, Anna found herself in the grip of an addiction. She was consumed with romance novels and erotica, and a note that this next part of the discussion involves references to sex. At one point she found herself swept up in the novel Fifty Shades of Grey. The story, later made into a movie, revolves around a sadomasochistic relationship between a college student and a business tycoon.
