1562-肌萎缩侧索硬化症认知障碍的细胞表型研究
from 聊聊Sci
本研究利用多模态空间生物学分析，探讨了肌萎缩侧索硬化症（ALS）患者额叶皮层的细胞与分子变化，揭示了认知障碍与特定神经胶质及神经元功能障碍之间的联系。研究团队通过整合单细胞转录组学与空间转录组学，发现语言能力下降与脑内广泛的胶质细胞及血管异常响应密切相关。相比之下，执行功能障碍则主要由背外侧前瞻性皮层深层神经元的线粒体与突触活动减少驱动。通过贝叶斯模型和多重成像技术，科学家证实了这些临床表现的差异性源于特定脑区的多细胞互作，而不仅仅由传统的蛋白病理引起。该成果强调了ALS认知临床表型的高度异质性，并为其复杂的病理机制提供了高分辨率的细胞图谱。References:Petrescu J, Roque C G, Jackson C A, 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.
