As neuroscience gains the power to record thousands of neurons at once and compare biological brains to artificial ones, it finds itself rich in tools but poor in consensus — more than thirty competing methods now claim to measure neural similarity, yet the field has not agreed on what similarity truly means. This is not merely a technical dispute; it is a philosophical one, echoing the oldest challenge in comparative science: whether resemblance is a surface pattern or a window into shared mechanism. The kidney researchers of the 1960s did not stop at correlation — they used it to reveal how

Confidence
HIGH
Problem-centered framing that presents comparative neuroscience as an evolving field grappling with legitimate methodological challenges. Uses historical examples (Darwin, kidney research) to establish credibility and normalize the comparative approach without advocating for specific solutions.
Perspectives from AI researchers or computer scientists on how they approach model comparison
Voices of neuroscientists skeptical of AI-brain comparisons or those questioning their validity
Practical implications or applications of these comparison methods
Ethical considerations around AI-brain analogies
Geopolitical Impact
🌎
This is a scientific article about neuroscience methodology, not geopolitics. It discusses comparative analysis techniques for studying brains and AI models without international, political, or strategic implications.

Delayed development of AI-assisted medical diagnostics, brain-computer interfaces, and neurological treatments; longer timelines for consumer applications in mental health monitoring and cognitive enhancement technologies.
Potential need for regulatory frameworks standardizing neural comparison methodologies; funding agencies may require consensus protocols before approving comparative neuroscience-AI research; international coordination needed to establish measurement standards for cross-institutional studies.
