#44 Meet the Neuroscientist Using AI to Unlock the Secrets of Language! Dr Evelina Federenko

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…
