600-人类大脑代谢连接组的构建与组织
from 聊聊Sci
该研究展示了如何利用磁共振波谱成像（MRSI）技术来构建代谢相似性矩阵（MetSiM），从而揭示人脑的代谢网络结构。研究人员通过分析日内瓦和洛桑两个独立群体的影像数据，发现脑区间的代谢图谱相似性具有高度的个体一致性。尽管代谢特征与物理上的大脑结构连接仅存在微弱的相关性，但代谢相似的区域往往会共同指向相同的结构目标。研究通过t-SNE降维和复杂网络分析，揭示了脑网络内部的局部和全局组织原则。此外，该论文详细介绍了利用高阶连接性和熵模型来评估大脑各区域间信息传递与代谢分布的复杂关系。这一成果为理解人类大脑的生化功能架构提供了全新的计算视角。References: Lucchetti F, Céléreau E, Steullet P, et al.

Deep Dream State
Neural Nets And Pretty Patterns
Deep Dream State is a full-cast dystopian sci-fi and desire horror audio drama by Neural Nets and Pretty Patterns. As the originating work of desire horror, it locates the uncanny inside wanting itself. While conventional horror positions you against a threat, desire horror implicates you in it. The horror emerges from recognition: the realization of why characters stay, and why surrender feels like relief. Since 2017, the show has used research in dream science, surveillance studies, behavioral economics, and advertising technology to examine systems of control through immersive sound design and full-cast performance.
