People who are distracted often cannot secrete and absorb dopamine normally in a boring environment. For example, people who are addicted to online games often rely on the high stimulation brought by online games to get attention. Once their stimulating environment is reduced, such as boring study courses and work, they are prone to drowsiness, and their brains cannot secrete dopamine in a low stimulating environment, which leads to their inability to concentrate on their studies. Long-term exposure to highly exciting online games makes it increasingly difficult for people to concentrate on simple tasks in daily life. Too little dopamine secretion can't concentrate, and the brain produces too many alpha waves and theta waves. Excessive dopamine secretion leads to excessive anxiety, and the brain releases high beta waves. Jingsi pilot star can find out the band SMR and low β wave when everyone is paying attention through the electric waves generated by the cranial nerve, and improve the effective wavelength of attention interval through real-time training. Brain nerve cells gradually get used to producing proper amount of dopamine in boring environment. At the same time, through training, we can restrain inattention and excessive anxiety, and finally make the brain develop the habit of using the brain efficiently, so as to significantly improve attention and learning efficiency.
