391-啮齿类动物脑网络连接障碍模型研究综述
from 聊聊Sci
这项研究探讨了利用大鼠和小鼠的功能磁共振成像（fMRI）来揭示人类精神与神经疾病中脑网络连接异常的生物学机制。尽管人类影像学能发现大脑连接的改变，但难以深入到细胞或基因层面进行因果分析，而动物模型通过先进的化学遗传学和光遗传学手段填补了这一空白。文章强调了啮齿类动物与人类在大脑网络组织上的高度相似性，证明了跨物种研究的转化价值。通过操纵特定的神经调节系统，研究者可以更精确地解析大脑动态变化的物理根源。最终，这种多模态的研究平台有望将宏观的影像标志物转化为具体的微电路功能障碍参数，为理解和诊断复杂的脑部疾病提供科学支撑。References: Modeling Brain Dysconnectivity in RodentsGozzi, Alessandro et al.Biological Psychiatry, Volume 93, Issue 5, 419 - 429前往小宇宙评论区与主播互动

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.
