项目摘要

In relating brain signals to cognition, the assumption is that behavioural processes will activate key regions of the brain. Much like a computer, the region is 'on' when the process it supports is required, and 'off' when the process is not required. Some critical features of brain organization suggest that we need to rethink this idea. Researchers have shown that the brain relies on both activity and variability to ensure optimal function, and that brain regions produce variable signal at all times (even when they are 'off' in the computer analogy). In fact, brain signal variability allows people to respond quickly and flexibly to environmental demands. Instead of a computer that turns on and off, think of the brain as a system in constant motion, and think of variability as the kinetic energy that allows this system to move easily from one network to another.
在将大脑信号与认知联系起来时,假设行为过程将激活大脑的关键区域。与计算机非常相似,当需要它支持的进程时,该区域为“开”,当不需要该进程时,该区域为“关”。大脑组织的一些关键特征表明,我们需要重新考虑这一想法。研究人员已经证明,大脑依靠活动性和变异性来确保最佳功能,而且大脑区域一直产生不同的信号(即使在计算机类比中,它们处于关闭状态)。事实上,大脑信号的可变性使人们能够对环境需求做出快速而灵活的反应。与其把计算机想象成一个不断运动的系统,不如把大脑想象成一个不断运动的系统,而不是一台能开关机的计算机,而是把变化性看作是让这个系统能够轻松地从一个网络移动到另一个网络的动能。
