Abstract
In 2001 Raichle and colleagues showed that, at rest, brain activity fluctuates near a metabolically active equilibrium: a 'default mode' of brain function. This finding broke ranks with the prevailing 'task-rest' dichotomy to position the brain as continuously active, balancing the deployment of resources according to current and anticipated needs.
摘要
2001 年，雷切尔（Raichle）及其同事表明，在休息状态下，大脑活动在代谢活跃的平衡附近波动：这是大脑功能的“默认模式”。这一发现打破了流行的“任务-休息”二分法，将大脑定位为持续活跃的状态，根据当前和预期的需求平衡资源的配置。
