Your brain may have a specific pace. The smarter it is, the more your brain will be in sync with your own secret pace, concludes a new study.
When your brain works intensely, different regions of the brain synchronize, working together to perform tasks that require greater cognitive load-reaction with the name of teta connectivity.
A new study has now concluded that this effect is highly flexible, quickly adapting to change situations, and that a Best brain coordination It is strongly correlated with cognitive capacity.
“Specific signs in the brain’s mediofrontal region are better synchronized in people with greater cognitive capacity, especially during demanding phases of reasoning,” says the psychologist Anna-Lena Schubertfrom Johannes Gutenberg University of Mainz, Germany, quoted by.
Teta connectivity, synchronized activity between brain regions of slow waves in the range of 4 a 8 Hertzis related to the brain’s capacity replenish mental burdenexplains the researcher.
A set of evidence suggests that it performs a paper significant in the cognitive function – a strong enough connection so that it can even be promising as a tool for diagnosis.
Schubert and his colleagues wanted to investigate teta connectivity as a cognitive control marker, the brain capacity to adapt and adjust the thought, and Behavior and emotions based on current tasks and contexts.
In the course of, published in Journal of Experimental Psychology: Generalthe researchers analyzed 148 people with ages Between 18 and 60 years and submitted them to tests to evaluate their Memory and Intelligence.
Each study participant wore a noninvasive electroencephalography (EEG) helmet to record their brain activity and received three tasks mentally challenging to complete.
In the first task, participants received digits between one and nine and had to indicate if the number was greater or less than fiveor if the number was even or odd.
In the second task, participants received Navon figures And they had to identify the large form or the small forms that made it up.
Finally, in the third task, Participants received pairs of numbers and letters and had to indicate whether the number was larger or less than five, or whether the letter was a vowel or consonant.
Brain investigation
None of the tasks itself is particularly difficultbut the researchers wanted to evaluate the speed with which participants adapted to a set of rules in constant change And if this was detectable in your cerebral waves.
To the surprise of the researchers, not only managed to observe the brain coordination in real time with rapid changes in tasksas well as participants who had Better performance in tests of intelligence and memory presented a Stronger tissue connectivity during these tasks.
“People with a stronger mediofrontal tissue connectivity are often more capable of keep focus and ignore distractionsWhether the phone is vibrating while working or intent on reading a book in a busy train station, ”says Schubert.
Found that one of the keys to better cognitive performance is not sustained attention, but the ability to switch tasks quicklyadapting quickly as circumstances require it.
The brain’s mediofrontal region works in conjunction with other brain regions, not only to prepare for tasks, but to perform decisions.
“These results significantly advance the theoretical models of intelligence, highlighting the Critical Role of Aspects Cognitive control specific in cognitive capabilities, ”says Schubert.
These findings not only help us understand the role that brain coordination plays in cognition, but can also open the way for brain investigation and help to substantiate New diagnostic techniques.
“Potential applications, such as training or diagnostic brain -based diagnostic tools, are still very distant, but our study offers an important basis for understanding How intelligence works at the neural levelSchubert concludes.
