Large Language Models Facilitate Brain-to-Brain Communication in Conversations
A study involving intracranial recordings during face-to-face conversations reveals that large language models (LLMs) effectively model the transfer of linguistic information between brains. By aligning neural activity to a shared linguistic space, LLMs capture the context-dependent exchange of thoughts, demonstrating how language production and comprehension are synchronized across individuals during natural communication.

During a conversation, the brains of the participants tend to synchronize, aligning neural activity patterns. This phenomenon, observed through neuroimaging studies, suggests that effective communication relies on this brain-to-brain coupling, facilitating understanding and connection. Synchronization is stronger in more engaging or meaningful interactions, reflecting the depth of shared understanding between individuals.
