Mapping Neural Networks to Strengthen Circadian Rhythms

Researchers in China have analyzed the network heterogeneity of the suprachiasmatic nucleus to ultimately reverse age-related decline in circadian rhythm

Most people have experienced some sort of grogginess the morning after traversing time zones. This is due to the mismatch of your body’s circadian rhythm and the current new local time. There is a region in the brain that is responsible for regulating this called the suprachiasmatic nucleus (SCN). This is a tiny region located just directly above the two optic nerves and is regulated on a neuronal and hormonal level. Travelling is not the only thing that can impact our rhythm. Aging plays a part in it as well; it can weaken the rhythm and cause sleep disorders, metabolic syndrome and depression. Although there has been evidence documented that age weakens the circadian rhythm, there are no answers as to how this actually happens. Researchers at the University of Shanghai for Science and Technology in China recently conducted an experiment of the SCN’s connections and how the nodes within its network work together.
