Fishing nemesis?

At the moment when involvement is serious, the work pressure is becoming more and more onerous, so there is such a group of people who use their own strength to practice the ideological procession and make silent complaints through "fishing"
.

"Fishing" is also really helpless, it is resistance to repressive work and life
.

In fact, lack of attention is a very common phenomenon, which is related to mind wandering (daydreaming) or blank thinking.
In this process, the stream of consciousness will be stopped
.

It is worth noting that these attention deficits occur more frequently when people are tired, and may be related to a neurological phenomenon called "partial sleep"-in which certain brain areas show signs of entering slow-wave sleep, while remaining The lower brain area remains alert
.

Recently, researchers from the Turner Institute of Brain and Mental Health, Monash University, Australia, published a titled: Predicting lapses of attention with sleep-like slow waves in the journal Nature Communications, a sub-Journal of Nature.
Lack of power) research papers
.

The study found that slow waves, a pattern of neural activity usually associated with transitions to sleep, can be used to predict whether people will daydream or have brain blanks, and their response to the environment
.

This neural activity may be important for understanding different states of consciousness
.

The human brain is the bearer of consciousness, and attention can direct cognitive resources to the outside world, and can select and amplify information related to the individual's current behavioral goals
.

At the same time, attention can also be turned internally.
For example, when we focus on internally generated thoughts that are not related to the task, this phenomenon is often called mind wandering
.

In fact, one of the characteristics of attention is its shortness, which means that we cannot maintain attention for a long time on a task
.

Some recent studies have shown that in the absence of sleep, people are more prone to thinking wandering or thinking blanks in a waking state
.

Thomas Andrillon et al.
proposed in a recent review: Partial sleep is manifested as slow waves when awake
.

This not only explains the behavioral consequences of lack of attention, including sluggishness and impulsive responses, but also explains their phenomenology
.

Not only that, they also believe that partial sleep is not an extreme phenomenon, and it can only happen when the individual is pushed to the limit.
Of course, the possibility of partial sleep is not ruled out in a well-rested person
.

Slow wave and sleep and wakefulness In order to verify this theory, Thomas Andrillon and his research team proposed the following three different hypotheses based on slow wave detection: (1) At the level of a single test, can slow waves predict well-rested individuals’ Slow and impulsive behavior? (2) Are slow waves related to thinking wandering and thinking blanks? (3) Can the position of the slow wave distinguish between slow and impulsive behaviors, wandering thinking and blank thinking? The local appearance of slow waves and behavioral modulation research team recorded the whole brain electrical activity of 26 well-rested adults during the continuous attention task through electroencephalogram
.

In the experiment, these participants needed to focus on images of faces or numbers for an average of 1.
7 hours
.

The researchers instructed participants to press buttons when they saw a specific facial expression or number to keep their attention
.

At the same time, participants were randomly interrupted every 30-70 seconds, and asked to explain whether their mental state was focused on the task, or whether thinking wandering or thinking gaps had occurred
.

In addition, the researchers also assessed the participants' drowsiness by measuring pupil size and task performance
.

Experimental design and hypothesis Researchers have found that slow waves in the forebrain area appear before thinking wandering and thinking gaps, and when slow waves occur in areas further behind the brain, such as the parietal lobe, they will be followed by brain gaps and slow reactions
.

The research team believes that this is a common neural feature produced by different brain regions before different states of consciousness
.

The local localization of slow waves can predict the subject’s state of mind.
In short, this study reported the spatial and temporal localization of the slow waves of local sleep through high-density EEG, and the location of the slow waves can still be seen.
Used to distinguish between slow and impulsive behavior, as well as thinking wandering and thinking blank
.

The results of these studies show that attention deficit has a common physiological root-local sleep-like activities in the waking brain
.

Therefore, we can also reversely predict whether attention is missing by detecting slow waves
.

Of course, Thomas Andrillon also pointed out that although the slow waves they found are very similar to those seen in sleep, they still need to be verified by other techniques such as intracranial records to determine whether they have a common basic mechanism
