957-星形胶质细胞连接大脑区域的塑性网络
from 聊聊Sci
这项研究开发了一种基于载体的星形胶质细胞网络追踪技术，能够以前所未有的精度观测大脑中间隙连接介导的通讯。研究通过全脑成像发现，星形胶质细胞并非盲目扩散，而是通过具有区域特异性的塑料网络精准连接特定脑区。这些网络在空间跨度上表现出多样性，既包含局限在单一区域的连接，也包含跨越半球的长程网络。此外，研究证实星形胶质细胞网络在功能上独立于神经元，且在感觉剥夺后会发生明显的结构重塑。这一发现揭示了大脑中除了神经元路径外，还存在一套由胶质细胞构成的动态通讯系统。References:Cooper M L, Selles M C, Cammer M, 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.
