- Brain scans indicate LLM users have half as many Alpha connections as those relying solely on their brains.
- A study by MIT, Wellesley College, and MassArt found AI reliance reduces brain connectivity and impairs memory recall.
- Participants using LLMs showed weaker semantic processing networks (42 Alpha Band connections vs. 79 in Brain-only group).
- Theta Band activity, linked to working memory, was significantly lower in LLM users (29 connections vs. 65 in Brain-only group).
- 83.3% of LLM users couldn't accurately recall their own essays, compared to 11.1% in Search Engine and Brain-Only groups.
- Repeated AI use leads to cognitive debt, diminishing critical thinking, creativity, and increasing vulnerability to manipulation.
- The study had limitations, including a small sample size of 54 university students from similar backgrounds.
