Creativity is the intricate dance of imagination and reason, weaving the tapestry of novelty from the threads of experience and dreams, pushing the boundaries of what was thought possible.

创造力是想象与理性的复杂交织，它将经验与梦想的线索编织成新颖的锦缎，不断突破人们曾认为可能的界限。

Default Mode Network

What Is the Default Mode Network? The default mode network (DMN) is a system of connected brain areas that show increased activity when a person is not focused on what is happening around them. The DMN is especially active, research shows, when one engages in introspective activities such as daydreaming, contemplating the past or the future, or thinking about the perspective of another person. Unfettered daydreaming can often lead to creativity. The default mode network is also active when a person is awake. However, in a resting state, when a person is not engaged in any demanding, externally oriented mental task, the mind shifts into “default.”

You know the feeling of walking to the train station for your morning commute, but your mind checks out and your body operates on autopilot. Your body goes through the motions of getting you to work without taxing the brain, all of which sounds beneficial. It is indeed useful, but only up to a point. The problem: You do not remember much about that commute because your default mode network kicked in, you may start with daydreaming, but you start to ruminate over what happened the day before and what will happen in the days to come. You are anxious about past performance, and you are anxious about upcoming performance. The default mode network can hijack the mind to mull over worries.

The default mode network is about self-focus and mental time-travel, and its inactivity appears to be related to varied forms of mental illness. The DMN is involved in episodic memory processing, with introspection and autobiographic memory as important cognitive processes. Researchers have reported dysregulation between the components of the default mode network in patients with Alzheimer’s disease as well as those with Parkinson’s disease, illnesses that affect memory processing.Connectivity between particular default mode network areas of the brain has been linked to higher levels of rumination in depressed individuals. The depressive among us ruminate about their regrets, failures, shame, and anger. Further links with default mode network dysregulation have been made to autism, schizophrenia, and other conditions.

The default mode network is more connected in the brains of lonely people. There is more activity in the DMN in the brains of lonely people. These people spend a lot of time thinking about what happened in the past and what will happen in the future, all with feelings of worry, anxiety, and dread.The DMN is also thought to play a role, in combination with other brain networks, in key qualities such as creativity. As a person idles and her mind drifts, the activity of the DMN may help give rise to ideas that other networks then vet and process further.

The default mode network, discovered by neurologist Marcus Raichle, spans a number of brain regions, incorporating parts of the prefrontal, parietal, and temporal cortices that show joint activation, or deactivation, in connection with particular mental functions. It is one of a number of such brain networks, which also include the salience network and the executive control network.The executive control network monitors what is happening around us, it manages emotional parts of the brain, it directs our attention, and is crucial in decision-making. It also helps process sensory and memory information.

We are insignificant in the grand scheme, and we do not have to stew in our troubles. 

let sb stew in their own juice   让某人自作自受

我们在宏伟的计划中微不足道，我们不必为烦恼而烦恼。 

The default mode network, discovered by neurologist Marcus Raichle, spans a number of brain regions, incorporating parts of the prefrontal, parietal, and temporal cortices that show joint activation, or deactivation, in connection with particular mental functions.

这是一个复合句，主句是：The default mode network spans a number of brain regions。discovered by neurologist Marcus Raichle 是过去分词短语作后置定语。incorporating parts of the prefrontal...是现在分词短语作状语，修饰主句.

翻译：神经学家Marcus Raichle发现的默认模式网络横跨许多大脑区域，包括前额叶、顶叶和颞叶皮层的部分，这些区域显示出与特定心理功能相关的联合激活或失活。

Any experience of awe, such as hiking to a mountain top or watching the moon rise or swimming in the ocean, can take you out of your mind. Your focus is not on everyday worries, but more on the big picture.
