Neuroscientist Ev Fedorenko has identified a specialized language network in the human brain that functions as a biological parser, mapping words to meanings stored elsewhere in the brain. This strawberry-sized system, located in the left frontal and temporal lobes, acts as an interface between perception and thought rather than generating thought itself. Her research reveals surprising parallels between this brain network and early large language models, both processing linguistic structure without deep semantic understanding. The language network responds equally to nonsense and meaningful sentences, suggesting it operates as a shallow, specialized system for encoding and decoding language rather than a core component of cognition.

What is the language network?That sounds very abstract. But you call the language network a “natural kind” — does that mean it’s something physical you can point to, like the digestive system?How is this different from other parts of brain anatomy known to be associated with language, such as Broca’s area (opens a new tab) ?You’ve also said (opens a new tab) that language isn’t the same as thought. So if the language network isn’t producing speech, and it’s also not involved in thinking, what is it doing?Sort:
