Medicine (Baltimore). You would think that its only role is to transmit information. But there is still a lot that we dont know about. How this occurs is not precisely known, but adenosine is one of the chemicals thought to accumulate during prolonged wakefulness. Scientists also study organisms with irregular circadian rhythms to identify which genetic components of biological clocks may be broken. Regulate passage of materials from the blood into the cerebrospinal fluid and the brain. Your body's internal clock is controlled by an area of the brain called the SCN (suprachiasmatic nucleus).
