Summary
Neuroscientist Ev Fedorenko has spent 15 years studying the brain's language network, discovering that language processing in the human brain shares some similarities with large language models (LLMs). Her research challenges the traditional view that language is central to thought, instead suggesting it may be a separate module. Fedorenko's work uses fMRI and other neuroimaging techniques to map the brain's language system, finding it operates independently from other cognitive functions like reasoning and social cognition. The article explores how her findings relate to AI language models and what they reveal about the fundamental nature of human language processing.
Key quotes
· 5 pulledEven in a world where large language models (LLMs) and AI chatbots are commonplace, it can be hard to fully accept that fluent writing can come from an unthinking machine.
Long before the rise of ChatGPT, the cognitive neuroscientist Ev Fedorenko was asking questions about how the brain processes language.
For 15 years, the neuroscientist Ev Fedorenko has gathered evidence of a language network in the human brain — and has found some similarities to LLMs.
That's because, to many of us, finding the right words is a crucial part of thought — not the outcome of some separate process.
But what if our neurobiological reality includes a system that behaves something like an LLM?
Is language core to thought, or a separate process? For 15 years, the neuroscientist Ev Fedorenko has gathered evidence of a language network in the human brain — and has found some similarities to LLMs.
