摘要

How does the human 大腦 encode complex visual 資訊? While previous research has characterized individual dimensions of visual representation in cortex, we still lack a comprehensive understanding of how visual 資訊 is organized across the full range of 神經 族群 activity. Here, analyzing fMRI responses to natural scenes across multiple individuals, we discover that 神經 representations in human visual cortex follow a remarkably consistent 無標度 organization-their variance decay is consistent with a power-law distribution, detected across four orders of magnitude of latent dimensions. This 無標度 structure appears consistently across multiple visual regions and across individuals, suggesting it reflects a fundamental organizing principle of visual processing. Critically, when we align 神經 responses across in
