标题： High-dimensional structure underlying individual differences in naturalistic visual experience

摘要： 不同大脑如何从相同的感官输入中创造出独特的视觉体验？ 尽管神经表征在个体之间存在差异，但这些差异背后的基本结构仍不清楚。 在这里，我们揭示了个体的视觉体验源于视觉皮层层级中的高维神经几何结构。 通过在自然电影观看期间对fMRI响应进行谱分解，我们发现个性化的神经模式在多个数量级的潜在维度中持续存在。 值得注意的是，每个维度范围编码了个体处理的不同定性方面，并且这种多维神经几何结构可以预测随后的记忆回忆中的行为差异。 这些细致的个体间变异模式无法简化为传统跨被试相关性测量所检测到的模式。 我们的研究结果表明，主观的视觉体验来自于在广阔多维流形上整合的信息。 这一几何框架为理解多样化的头脑如何从共同的体验中构建独特的感知世界提供了一个强大的新视角。 显示英文摘要

摘要： How do different brains create unique visual experiences from identical sensory input? While neural representations vary across individuals, the fundamental architecture underlying these differences remains poorly understood. Here, we reveal that individual visual experience emerges from a high-dimensional neural geometry across the visual cortical hierarchy. Using spectral decomposition of fMRI responses during naturalistic movie viewing, we find that idiosyncratic neural patterns persist across multiple orders of magnitude of latent dimensions. Remarkably, each dimensional range encodes qualitatively distinct aspects of individual processing, and this multidimensional neural geometry predicts subsequent behavioral differences in memory recall. These fine-grained patterns of inter-individual variability cannot be reduced to those detected by conventional intersubject correlation measures. Our findings demonstrate that subjective visual experience arises from information integrated across an expansive multidimensional manifold. This geometric framework offers a powerful new lens for understanding how diverse brains construct unique perceptual worlds from shared experiences.
