Mouse study reveals the presence of the Baml1 gene in the striatum has a sexually dimorphic effect on alcohol consumption. Male mice without the protein consumed more alcohol than those who did, while the reverse was true for females.
A new study reveals astrocytes play an surprisingly important role in the body's circadian clock.
A newly developed microfluidic device allowed researchers to keep tissue from the suprachiasmatic nucleus alive for over 25 days.
Researchers have discovered a group of neurons in the retina that affect circadian rhythm by sending signals to the SCN.
The circadian CLOCK gene in the nucleus accumbens shell plays a crucial role in binge drinking behaviors in mouse models.
During wakeful periods, the glymphatic system diverts cerebrospinal fluid to lymph nodes in the neck. The CSF may act as a "fluid clock" that helps initiate the body's infection-fighting capabilities during the day. Astrocytes in the suprachiasmatic nucleus may serve to control CSF through the central nervous system. Communication between astrocytes in different brain regions may optimize the glymphatic system's function as we sleep.
Circadian rhythm could be key for helping overcome addiction, a new study reports.
Researchers report proteins associated with immunity and metabolism can become disrupted following just one simulated night shift.
Daily release of glucocorticoids depends on coordination between the clock gene and activity rhythms of neurons within two parts of the hypothalamus.
Neurons in the suprachiasmatic nucleus coordinate to adapt to different lengths of daylight, changing at cellular and network levels. The neurons changed in mix and expression of dopamine, altering brain activity and subsequently daily routine behaviors.
Researchers have identified a molecular pathway that appears to regulate between sleep and wakefulness.
Researchers have discovered an important mechanism which allows animals to effectively track seasonal changes.
