Description

There’s a significant mismatch between our ancient brain's capabilities and the rapid advancements in technology. Simply put, our brains just can’t keep up in the digital age. But what does that impact look like from the brain’s point of view? What’s really going on with the neurotransmitters when we take in all that information? Richard Cytowic is a professor of neurology at George Washington University. His books like Your Stone Age Brain in the Screen Age: Coping with Digital Distraction and Sensory Overload and The Man Who Tasted Shapes examine the effects of technology on the brain and explore the rare but very real phenomenon of synesthesia. Richard and Greg chat about the energy economics of brain function, the inherent limitations of multitasking, and the benefits of a digital detox. They also explore synesthesia, how human neurology is uniquely wired for metaphor, and how babies might all have some form of synesthesia early on. *unSILOed Podcast is produced by University FM.*Episode Quotes:Why multitasking is exhausting your brain04:05: Our brains today are no different from those of our distant ancestors. I mean, they have not evolved one iota, whereas technology has been advancing ten thousand, a million times more than that. So I do think we've reached the point where we're asking it to do what it simply can't do anymore. The brain has a fixed level of energy that it can use, and no amount of diet, exercise, supplements, or Sudoku puzzles can possibly increase that. So when you're asking it to multitask or to keep switching attention from one thing to another, you're asking it to do things that it was never designed to do, that it can't do very well, if at all. And so that's why people are burned out and fatigued.Why are people so concerned about what they put in their bodies, but not about what their mind consumes?35:13: People are so concerned about what they put in their bodies—non-GMO, vegan, no sugar, no artificial colorings. But why aren't they as picky about what they ingest through their senses? I mean, the mental garbage that we take in is certainly less harmful than the occasional cheeseburger and Twinkie. So people just don't think in terms of, "What is my sensory diet?" And again, I'm so unusual because I'm thinking neurologically and neuropsychologically, and most people never have the opportunity or the inclination to think about the way that they think—this metacognition kind of thing.Quiet is an essential nutrient 15:03: Quiet is the antidote to everything. I call it an essential nutrient. We need it to give ourselves space to think. And part of it has to do, I think, with people feeling that they don't like solitude. They think being alone is an odious, difficult state. But I say that solitude has. Loneliness wants. And so if you can distinguish between the two—that here, sitting in a park with a tree and a green space, and I'm quite happy, eating my lunch here in solitude—then this is a positive experience for me. I'm giving myself a nourishing experience. But if I'm thinking, Oh my God, I'm all alone. There's nobody to talk to. I don't know what to do; you're doing a number on yourself and freaking yourself out.The iPad as babysitter29:52: The iPad is the worst babysitter in the world. Look at a baby when they get to be on the move and start crawling. They put everything in their mouths. They're touching, feeling, and having a visual apprenticeship with the world. And when you put this screen full of mediated images in front of them, those characters, if they're Disneyfied or not, don't engage with the child in the same way that a real human being does. They talk at a child. They don't talk with a child. Whereas an adult who's playing peek-a-boo, and "so big," and other kinds of things like that, they're speaking to the child in normal adult language. And these kids are picking things up like sponges, believe me, and that's what they need to have. They need to have that one-on-one interaction.Show Links:Recommended Resources:What percentage of your brain do you use? | TED-EdWilliam JamesClifford Nass Her (film)Bernard-Henri LévyThe Revenge of Analog: Real Things and Why They Matter by David SaxDaphne MaurerGuest Profile:Faculty Profile at George Washington UniversityProfessional WebsiteLinkedIn ProfileHis Work:Your Stone Age Brain in the Screen Age: Coping with Digital Distraction and Sensory OverloadSynesthesia The Man Who Tasted ShapesWednesday Is Indigo Blue: Discovering the Brain of Synesthesia Hosted by Simplecast, an AdsWizz company.
