Research questionWhat can LLM–brain representational alignment establish about shared neural mechanisms—and what can’t it?Similar representational patterns in an LLM and the brain may reflect shared information without revealing how either system computes. Multiple mechanisms can produce the same alignment, creating logical, causal, and computational underdetermination.
