AI causes reduction in users brain activity MIT

A study conducted by MIT reveals that the use of large language models (LLMs) like ChatGPT diminishes neural activity in users' brains, leading to reduced cognitive engagement during tasks such as essay writing. Using EEG monitoring, researchers observed that participants relying on AI exhibited significantly lower neural connectivity and grey matter activity compared to those working without technological aids or with traditional search engines, indicating that AI assistance lessens mental effort and strategic engagement. Furthermore, the study highlights a decline in the sense of ownership and recall of written work among AI users, with participants demonstrating diminished ability to quote or summarize their own contributions.
