Japanese scientists have come to the conclusion that the chewing process has a positive effect on cognitive function of the brain, while improving short-term memory, reaction speed, concentration, reports the Daily Mail.
Conclusion Japanese scientists have made based on the results of the study, which was attended by 17 volunteers in the age group 20 to 34-ex years. The scientists asked the participants of the experiment for half an hour to run the test on logic and attentiveness, while chewing a chewing gum that does not contain neither taste nor smell. It was made with one purpose - to exclude any side effect that could be left to taste or smell. During the experiment the activity areas golovnogo brain were measured by MRI.
The study showed that chewing process significantly reduced the length of time that was allotted for the job. It turned out that chewing volunteers by 10 percent faster coped with the task, and additionally the quality of the performed tests was also high.
In addition, the study found that during mastication in humans in the brain are activated eight areas, from which most of all - the left frontal gyrus and the anterior cortex of the belt. These areas are "responsible" for motor function and attention. According to scientists, the process of chewing improves blood flow to these areas, which, in turn, improves cognitive function. At the same time, scientists have noted that the study should be continued, as this phenomenon is not yet fully understood.
