Scientists have identified a gene, Lhx1, that regulates sleep and wake rhythms.
The discovery of the role Lhx1 provides scientists with a potential therapeutic target to help night-shift workers or jet lagged travelers adjust to time differences more quickly. T

The master clock responsible for establishing these cyclic circadian rhythms and keeping all the body's cells in sync is the suprachiasmatic nucleus (SCN), a small, densely packed region of about 20,000 neurons housed in the brain's hypothalamus.
