Fakhar与Astle:人脑连接组并非最优,而是多目标权衡的产物

Embracing the suboptimal organization of the human brain

AI 导读

Kayson Fakhar与Duncan E. Astle在《Trends in Cognitive Sciences》发表观点文章,主张把人类脑结构视为最优模板的前提是错误的:依据摘要,在任一单一目标(如最小布线成本或最大通信效率)下,人脑连接组都是次优的,其组织反映的是进化与发育过程中在生物和环境约束下进行的多目标权衡。

摘要

Human brain architecture is guiding brain-inspired artificial intelligence (AI) and has been treated as an optimal template, whose deviations could mark different psychiatric and neurological conditions. We argue this premise is wrong: under any single goal (e.g., minimal wiring cost or maximal communication efficiency), the human connectome is suboptimal. Instead, its organization reflects multi-objective trade-offs navigated over evolution and development under biological and environmental constraints. For psychopathology, atypical trajectories are not distances from an ideal brain but reweighted compromises in the same trade-off space. For neuro-AI, directly duplicating the brain’s connectivity risks copying its irrelevant compromises. Treating brains and models as products of multi-objective optimization and co-tuning relevant objectives offers a more powerful framework for interpreting clinical phenotypes and designing next-generation AI.
