596-首个果蝇全脑连接组注释与细胞分型
from 聊聊Sci
这项研究报告了成年果蝇全脑连接组（FlyWire）的完整测绘与系统性注释，该图谱包含约13.9万个神经元及1500万个突触连接。研究人员通过整合形态学和连接性数据，构建了一个包含8453种细胞类型的庞大目录，这是目前已知最详尽且经过多样本验证的神经元分类集。通过对比不同个体的脑部数据，科学家证实了果蝇神经网络具有高度的稳态性和对称性，并非随机产生的个体特例。此外，文中还探讨了发育过程中谱系起源对神经环路形成的决定作用，并提供了识别关键功能边缘的技术标准。这套开源的数字化资源为研究复杂行为的神经基础提供了结构化导航，显著降低了脑科学建模的复杂度。References: Schlegel P, Yin Y, Bates A S, 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.
