1524-皮层主导：人类记忆形成的快速转换与增强
from 聊聊Sci
这项研究通过对人类大脑进行多日连续的颅内电生理记录，揭示了记忆形成的动态机制。研究发现，在学习后的第二天，大脑海马体与新皮层之间的相互作用便会发生显著的快速重组。关键结论指出，随着记忆的巩固，脑电波中的涟漪振荡耦合强度会大幅提升，且信号主导方向会从海马体转变为以新皮层为主导。这种方向性的逆转表明，新皮层比传统理论认为的更早参与并主导了长期记忆的整合。此外，海马体与皮层的涟漪发生率与个体的记忆表现呈现出明显的正相关关系。这一发现挑战了传统的缓慢巩固模型，为理解人类大脑如何迅速稳定存储信息提供了新的科学视角。References:Wang L, Duan Q, Song J, 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.
