Dr. Evelina Fedorenko is a cognitive neuroscientist at MIT and one of the world’s leading experts on how the brain processes language.

She’s mapped the brain’s language system more precisely than anyone, proving it’s a specialized network — not shared with general thought — and that our inner monologue? It might be an illusion. Now, her lab is using large language models like GPT to predict and even control neural activity in human language regions, revealing uncanny parallels between artificial and biological intelligence.

Expect to learn why you don’t actually think in words, how language and thought are distinct systems in the brain, why GPT-style models light up the same brain regions as human speech, what “drive” and “suppress” sentences reveal about how we process meaning, how hyperpolyglots learn 20+ languages using the same neural real estate, how bilingualism changes your brain, what language does that other mammals never evolved, how AI could reshape neuroscience research, whether machines could ever be conscious — and much more…
