Scientists from the University of Otago in New Zealand have found that the brain cells responsible for the settlement of stress operate according to their internal rhythm, about once at full recreation. The work was published in PNAS magazine.
It turned out that the neurons producing corticotropic-release hormone in the hypothalamus not only respond to threats, but they initiate activity cycles related to the changes in the level of wavy and the level of behavior. These "outbursts" took about 15 minutes and took place every hour, and more often during the active phase of animals.
"We were surprised how tightly the rhythms of the neurons of stress are associated with physical activity (irritation) rhythms. This has never been proven before, "said Head of the study Carl Iromonger.
Attempts on mice and rats showed that such cycles were often preceded not only to the beginning of the movement, but also for the release of stress hormones. Moreover, the artificial stimulation of neurons in recreational animals caused a sharp increase in motivation.
Scientists believe that these time "connections" of the stress system operate as an embedded awakening signal, preparing the body for activities. Violations of such rhythms can affect sleep and mood, as well as to play a role in the development of depressive disorders.
