Neural networks play a key role in regulating circadian rhythms through the mediation of cAMP. The findings may help with developing new strategies to manage circadian rhythm problems such as sleep disorders.
NG2-glia, a newly discovered type of brain cell that can renew itself is regulated by circadian rhythms. The findings shed new light on how the body's circadian clock can promote healing following a traumatic brain injury.
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.
A reconstituted circadian clock of cyanobacteria can run for consistent days, allowing researchers to study the interactions of the clock proteins in real-time and observe how the clock exerts control over gene expression.
