“A recent MIT study used EEG (electroencephalography) to examine what happens in the brain when people use AI tools like ChatGPT. The results were chilling. Brain activity dropped — especially in the prefrontal and temporal lobes, the areas responsible for problem-solving, planning, memory, and language. Even after removing the AI, participants who had used it showed persistently lower brain engagement. This lingering drop — dubbed cognitive debt — is eerily similar to patterns we see in screen-saturated youth or early cognitive decline.”
