Where does brain hole come from? New research from the University of California: creative people's neural connections will "take shortcuts"

Why are some people more creative ？ Always think of things that others will not think of , Do something others can't think of ？

lately , The answer to this question has been found ： Creative people , Neural activity in the brain will “ Take a shortcut ”.

Researchers at the University of California, Los Angeles, found , Creative groups like visual artists or scientists , There are more random connections in different regions of the brain , So it's easier to connect the brain Different areas .

This jumping brain connection , It is the source of extraordinary creativity .

Experimental process

The whole experiment is divided into 3 Stages ：

The first is to make sure that Subjects .

To verify the relationship between creativity and brain connection , The research team divided the experimental samples into 3 Group , Two of them are the observation group , By scientists （SCI） And visual artists （VIS） form , Each group 21 people .

What the members of the observation group have in common is , Engage in creative work , Have creative thinking , That is what researchers define “Big C” Type thinking .

The other group was the control group , from 21 Community volunteers ,

At the same time, the research team guarantees , In addition to the variable of creativity , Ensure the age of all subjects 、 one's ethnic background 、 Intelligence and other factors are roughly the same .

After confirming the experimental object , The researchers also conducted a special survey on everyone CAQ test , Make sure SCI and VIS The creativity of the two groups does have an advantage over the control group .

Next is Experimental method .

simply , It's in the subject's brain 3 In two states , Perform an MRI scan , Then extract the local and global graph theory of the brain , Use R lme4 Statistical package for statistical analysis , To verify that in different states , Differences in brain connectivity between different groups .

According to the experimental design , So-called 3 The brain states are as follows ：

• Stationary state ： continued 6 minute , The subjects were required to lie flat with their eyes open , Watch the white fixed cross on a black background ;
• AUT： continued 10 minute , Ask participants to think of as many different uses or typical qualities of the words in front of them as possible , And press the button for each different word , such as “ Umbrella ” My quality is “ waterproof ”, At the same time, it has waterproof performance , also “ hat ”;
• Remote correlation test （RAT）： continued 14 minute , Ask participants to identify 3 A seemingly unrelated word .

What is the result of the experiment ？

Results show , Creative scientists and visual artists , There are more in the brain “” Global random connection mode **, These global random connections , It can make people's ideas break through a small area , Produce more creative results .

The specific term , That's true ：

The research team found that , In global connection analysis , Under static state SCI Group and VIS Group B showed decreased connections in the small world of the brain , Compared with the observation group, the small world connection is also lower .

there Small world connection , It is a key indicator for the study of dynamic brain networks and creativity , Small world connection high , Prove that brain network connection is more efficient , Brain connection nodes are more concentrated .

In local connectivity analysis ,SCI and VIS Groups show higher local efficiency and clustering coefficient in static networks , And in the AUT State, , But the opposite is true , The local efficiency and clustering coefficient are lower than those of the observation group ,RAT In the process 3 There is no significant difference between the groups .

At the same time, researchers also found , At rest , There is a negative correlation between global clustering and local clustering ,

Description of the above function connection , With special creativity SCI and VIS Group , Have more brain global random connection patterns , In this mode, the small world connection is lower , In the case of dynamic thinking, the brain network Poor efficiency .

But the advantage is that it provides more possibilities for creative results .

Because there are more global random connections , It can make more connections between different brain regions .

How to understand that ？

A simple analogy , Ordinary people's brain connections and ways of thinking , Like a fixed route flight , Reach the remote unknown area , Need to experience different route hubs .

But the boss with creative thinking thinks about problems , It's like taking a private plane , You can open a new route to arrive directly .

But the randomness of this connection is also doomed , The new route is not necessarily correct , It is more likely to go wrong , Not as efficient as fixed routes .

besides , The analysis results also show , In a state of rest , People with higher creativity , Local areas of the brain have higher processing power ,

Tut tut tut , It turns out that the big guys can make breakthroughs in unknown fields , yes “ The brain took a shortcut ”.

It's true that I envy .（ Manual formation ）
