from Mind Spectrum · host The Cognitive Lab
Your Left Brain Is Sabotaging Your Life - And How to Stop It in 90 SecondsIn 1996, Harvard neuroscientist Dr. Jill Bolte Taylor had a massive stroke - and became one of the few scientists to describe her own brain’s deterioration from the inside. What she discovered about the two hemispheres may change how you understand negative emotions.Your left brain is often described as a serial processor that categorizes, worries, and generates internal chatter. It’s where much of your “I am” narrative seems to live - the voice that says you’re not good enough, or replays awkward moments from three years ago.But here’s the key idea: the physiological wave of an emotion may last about 90 seconds. After that, you’re not just “feeling” - you’re often feeding a storyline.What you’ll hear:How Dr. Jill Bolte Taylor’s stroke quieted her left-brain processing - and the profound shift in consciousness that followedThe 90-second rule: why emotional waves can peak and fade faster than we thinkHow the Reticular Activating System, or RAS, turns your brain into a social media algorithmThe “white bear” experiment: why fighting thoughts can make them strongerA 5-minute clinical protocol to interrupt negative thought cyclesYou are not your thoughts. You are the observer. And which circuitry you reinforce may be more flexible than it feels.More Mind Spectrum:EP35: Why IQ Tests Are Measuring the Wrong Thing - https://open.spotify.com/episode/4JCas6ziBT3mL8dZjV943yEP34: Why Your Need to Feel Safe Is Keeping You Anxious - https://open.spotify.com/episode/1BUSfr9Ym1ot8naUsTbTdnEP33: Your Child’s DNA Is Hiding Inside Your Brain - And Scientists Finally Know Why - https://open.spotify.com/episode/6LIwoOPDrxRoxN3R1jFbunEP31: The World Is Upside Down - 4 Truths of Spiritual Awakening - https://open.spotify.com/episode/2z9mhyxsgnkxytWE6tWlPCSubscribe to Mind Spectrum on Spotify for weekly deep dives into the neuroscience of human behavior.#MindSpectrum #Neuroscience #Psychology #MentalHealth #Anxiety #Brain #JillBolteTaylor #90SecondRule
