#134 Most Followed Neuroscientist: The Effects of AI on Your Brain
BigDeal Podcast Recap

Duration: 1 hr 12 min
Guests: Emily McDonald
Summary
This episode discussed the impact of AI on brain function and perception, focusing on how AI can create dependence and affect critical thinking. The conversation also explored neuroplasticity, perception, and the psychological effects of AI-generated content.
What Happened
Emily McDonald, one of the most followed neuroscientists globally, discusses a study with kittens that demonstrated how their visual environment altered their perception, underscoring the brain's role in constructing reality. This foundational idea sets the stage for a broader discussion on how frequent AI use may lead to dependence rather than fostering true intelligence.
The episode touches on traits like self-control and reliability, which are seen as attractive by the opposite sex, and links discipline to nervous system regulation. It also highlights how brain wave synchronization between people during communication can impact feelings and interactions.
Complaining and judging are shown to cause stress and negative neuroplasticity, shrinking the prefrontal cortex. To counteract this, reappraising situations after venting is advised to avoid reinforcing negative thought patterns.
Automatic goal contagion is explained as the subconscious adoption of others' goals, which can lead to unfulfillment if they don't align with personal values. The effectiveness of positive reinforcement over negative reinforcement in relationships is emphasized.
AI's influence is further examined, noting that while it can assist with organization and reduce monotony, it does not foster critical thinking. The episode warns that AI-generated content may feel disconnected, highlighting the beauty of human imperfection.
Emily McDonald also discusses the importance of balance, noting that work-life balance is often a misconception. Instead, balance should be found between periods of growth and output and periods of input.
The episode concludes with insights into the role of the reticular activating system in filtering information and recognizing opportunities. By priming the brain, individuals can change perception and improve performance.
AI's role in shaping perception and behavior is compared to the human tendency to see color uniquely due to individual brain construction. This concept extends to how AI can create content that appears real but lacks depth, reinforcing the need for fact-checking and critical engagement.
Key Insights
- Frequent use of AI can lead to dependence rather than fostering genuine intelligence, as seen in a study from MIT where AI use reduced brain engagement and critical thinking.
- Complaining and judging can lead to stress, negative neuroplasticity, and shrink the prefrontal cortex, while positive reinforcement is more effective for fostering healthy relationships and interactions.
- The reticular activating system filters vast amounts of information, allowing only 50 bits per second to reach conscious awareness, and can be primed to change perception and improve performance.
- AI-generated content can feel disconnected, highlighting the value of human imperfection, and underscores the importance of fact-checking due to AI's ability to create realistic yet false content.
