Your Brain on ChatGPT with Nataliya Kosmyna
The hosts speak with MIT Media Lab research scientist Natalia Kozmina about her study "Your brain on ChatGPT," which investigated how using large language models (LLMs) for essay writing affects brain activity, memory, and sense of ownership compared with using a search engine or no tools. They discuss her findings on reduced functional connectivity when using ChatGPT, more homogeneous writing, weaker recall, and diminished ownership, and explore broader implications for cognitive load, education, professional skills (such as medicine), mental health, AI companions, and the need for ethical guardrails and human‑focused research around AI and future brain‑computer interfaces.
