It is known that a 24-hour circadian rhythm controls nearly all brain and body processes, such as the sleep/wake cycle, metabolism, alertness and cognition. These daily activity patterns are regulated by certain genes that are found in almost all cells.  However, these genes have rarely been studied in the human brain.  Now, a study from researchers at the University of Pittsburgh has examined thousands of … Continue reading Researchers map the circadian neurogenetics involved in brain aging.
