941-7T磁共振成像揭示人脑稳态与内感映射
from 聊聊Sci
这项研究利用7特斯拉超高场强磁共振成像技术，精确绘制了人类大脑中的稳态-内感系统。该系统通过预测性处理来调控身体的代谢需求，并整合来自内部器官的感知信号。研究人员证实了人类大脑中超过96%的解剖连接与非人灵长类动物的示踪研究结果相吻合，显著提升了对脑干核团及扣带回等微小结构的绘图精度。研究发现，该系统由默认模式网络和突显网络组成，且其核心区域与大脑信息整合的“富人俱乐部”枢纽高度重合。这些成果表明，稳态调节与内感作用不仅是生理控制的核心，更是支持认知、情感和决策等复杂心理活动的底层架构。References:Zhang J, Chen D, Deming P, 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.
