Stay Awake And Check Dopamine Level

The exhaustion level is not the same in every human being. Some do not get exhausted even after a sleepless night. But some become very tired and exhausted for hardly one hour of shortage in their sleep time. The difference is mainly due to the level of dopamine chemical in our brain which differs from one person to another. Brookhaven National Laboratory in New York proved the statement by appointing 15 healthy volunteers who took a test on dopamine levels. The test was made twice, one after a sleepless night; other was after a good sleep. The scientists tested the levels of dopamine for both the tests. When they were awake, the dopamine levels went up in striatum and thalamus, two parts of the brain. The striatum reacts to the motivation and thalamus controls the alertness. Dopamine levels play a very important role in controlling the sleep.
