260-小鼠端脑GABA能神经元分类和空间图谱
from 聊聊Sci
这篇文章对哺乳动物脑部端脑中的 GABA能神经元 进行了全面且深入的转录组学和空间分析。研究人员利用大量的单细胞转录组数据，构建了一个分层的细胞类型分类系统（分类、亚类、超类型和集群），涵盖了小鼠端脑所有区域的 GABA能神经元。此外，研究还追踪了这些神经元的发育起源和轨迹，发现细胞类型关系反映了空间位置和胚胎发育起源，并且许多相关细胞类型通过长距离迁移分散在不同脑区。研究结果揭示了空间基因表达梯度，以及皮层和纹状体神经元与隔膜、视前区和苍白球神经元在出生后分化时间上的显著差异，为理解端脑 GABA能回路的组织提供了基础性参考。References: van Velthoven C T J, Gao Y, Kunst 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.
