After dopamine is released from the limbic system of the cerebral cortex to other parts of the brain, it can arouse people's happiness and work motivation, and it also plays a key role in people's sobriety. According to the PET three-dimensional imaging technique, scientific researchers found that the concentration of endogenous dopamine in striatum and midbrain of people deprived of sleep quality increased, and the nonspecific fusion of dopamine protein kinase radioactive substance coordination ([1 1C] laclopramide) decreased significantly. It shows that the dopamine level in the brain will increase after sleep deprivation, which plays a key role in promoting the maintenance of ascension. In other words, not sleeping at night leads to the increase of dopamine concentration in the brain, which makes us more and more energetic.
