Linux's Bedtime Routine
How does Linux move from an awake machine to a hibernating one?
How does it then manage to restore all state?
These questions led me to read way too much C in trying to figure out
how this particular hardware/software boundary is navigated.

抑郁症患者脑部特定神经网络较大
2024-09-09 23:03 by 消失吧！书本
根据发表在《自然》期刊上的一项研究，抑郁症患者脑部被称为“frontostriatal salience network（额叶纹状体突显网络）”的区域比健康人平均大 73%，即使情绪症状缓解或消失，该区域也不会缩小。大脑可按各区域功能连接分为不同的子网络，其中“突显网络”由多个与认知和情感相关的区域组成，它负责监测外部世界，并谨慎决定其他大脑网络对于新信息与刺激的反应。研究人员对 135 名重度抑郁症患者的大脑进行了功能性磁共振成像，发现他们大脑的“突显网络”比对照组的健康人更大，该区域在大脑皮层中的占比最多达健康人的约两倍。研究小组还分析了一项追踪儿童脑部发育的大规模研究的数据，在 1.2 万名调查对象中，有 57 名儿童在青春期患上抑郁症。数据显示，尽管这些后来患上抑郁症的儿童在 13 岁之前尚未出现症状，但他们脑部的“突显网络”在 9 岁时就比同龄健康人更大。研究人员推测，较大的“突显网络”可能与遗传有关，而人在抑郁状态下持续关注负面刺激，可能导致“突显网络”过度使用，从而使该区域进一步扩大。
