ChatGPT Use Reduces Cognitive Connectivity in Users

Researchers, including an MIT study published mid-2025, report measurable cognitive costs tied to regular ChatGPT and LLM use, using EEG and four-month tests showing lower neural connectivity and weaker recall among AI-assisted writers. Complementary studies in the Medical Research Archive and at Lancaster suggest over-reliance can erode essential skills and distract students, while learning outcomes remain mixed; authors recommend balancing AI assistance with human-led learning.
