Brain Experts WARNING: Watch This Before Using ChatGPT Again! (Shocking New Discovery)

Steven Bartlett sits down with psychiatrist Daniel Amen and computational neuroscientist Terry Sejnowski to examine how large language models like ChatGPT are affecting the human brain. They dissect a non-peer-reviewed MIT study showing a 47% drop in brain activity when people wrote with ChatGPT, debating whether AI builds 'cognitive debt' or, used interactively, can sharpen thinking. The conversation widens to AI companions like Grok's 'Annie', the loneliness epidemic, and the dangers of AI for developing young brains. The second half becomes a practical guide to brain health: exercise, sleep, the spacing effect, omega-3s, breathing, and avoiding artificial sweeteners. It closes with Bartlett resolving to 'do it the hard way' and think for himself when thinking matters.

• MIT study found a 47% collapse in brain connectivity when people wrote with ChatGPT versus unaided, with memory scores plunging.
  00:04:40
• Amen stresses the alarming MIT study is NOT peer-reviewed, as the authors rushed it out because they felt it was too important to wait.
  00:06:46
• A meta-analysis of five studies linked SSRIs to a 75% increased risk of dementia.
  00:09:21
• Sejnowski calls Sam Altman's advice to stop saying 'thank you' to ChatGPT 'completely crazy' and says he wouldn't trust Altman with anything.
  00:20:45
• Amen compares sexy AI characters to a Vegas casino: they activate the limbic brain, shut down the prefrontal cortex, and exist for control and money.
  00:30:08
• Amen claims that if you don't believe in God you have three times the risk of depression.
  00:58:38
• A brand-new study found kids who took ADHD medication had larger prefrontal cortexes than unmedicated kids with ADHD.
  01:13:09
• Bartlett concludes his big hedge for the next decade is to 'go left when everyone goes right' and refrain from AI, doing the hard thinking himself.

• In the MIT study, 83% of ChatGPT users couldn't correctly quote their own finished essay minutes later.
  00:05:12
• The 'cognitive debt' lingered: the AI group's brains stayed in low gear even after the tool was removed.
  00:05:44
• Alzheimer's onset is earliest in low-education populations and progressively later with more education.
  00:08:20
• Surveys show 19% of Americans have interacted with AI romantic partners, and 83% of Gen Z believe meaningful AI connection is possible.
  00:31:40
• Amen's '15-second breath': 4 seconds in, hold 1.5s, 8 seconds out, hold 1.5s, to boost parasympathetic tone and calm down fast.
  01:03:54
• Overuse of GPS navigation weakens the hippocampus by outsourcing spatial memory, potentially accelerating dementia onset.
  01:04:56
• In an experiment, mice taught to fear cherry-blossom scent passed that fear to their children and grandchildren epigenetically.
  01:05:59
• Depression doubles a woman's risk of Alzheimer's but quadruples a man's risk.
  01:16:45
• A JAMA Psychiatry study found a single sauna bath significantly helped depression, and frequent sauna users have the lowest Alzheimer's risk.
  01:20:20
• Amen's top three for brain health: exercise, daily optimism/gratitude, and omega-3 fatty acids (25% of brain cell membranes are omega-3).
