耗时15年、扫描1400个大脑，她发现了藏在人脑中的“生物版ChatGPT”

Core Insights - The research by Ev Fedorenko identifies a specialized language network in the human brain, likened to a "biological version of ChatGPT," which focuses solely on mapping words to meanings and constructing sentences, separate from thought and emotion [1][3][30] - Fedorenko's findings suggest that language serves as an interface for thought rather than being synonymous with it, challenging the common perception that finding words is an integral part of thinking [2][34] Group 1: Language Network Characteristics - The language network is described as a compact system, roughly the size of a strawberry, that connects external inputs (like auditory and visual stimuli) to other brain regions responsible for meaning representation [6][11] - This network is distinct from other brain areas associated with language, such as Broca's area, which is more involved in the planning of speech actions rather than the processing of language itself [17][18] - Fedorenko's research has established a probability map of the language network's location in the brain, showing consistent patterns across approximately 1400 scanned individuals [16][11] Group 2: Functionality and Implications - The language network operates as a "mapping warehouse," continuously updating the relationships between forms and meanings, enabling both expression and comprehension of language [21][22] - Damage to this network can lead to aphasia, where complex thoughts remain unexpressed, highlighting the critical role of this network in communication [8][7] - Fedorenko's work indicates that the language network can respond similarly to meaningful and nonsensical sentences, suggesting its function is more superficial and focused on structure rather than deep semantic understanding [28][29] Group 3: Research Background and Development - Fedorenko has spent 15 years gathering biological evidence for the language network, culminating in a comprehensive review published in 2024 [5][11] - Her academic journey began with a focus on linguistics and psychology, leading to her exploration of the brain's language processing capabilities [10] - The research emphasizes the specialization of the language network, which operates independently from higher-level cognitive functions, reinforcing the idea that language processing is a distinct and specialized function [36][30]
