WebMar 2, 2024 · Researchers believe this movement may stimulate the carotid artery, leading to an increase in heart rate and the release of wake-promoting hormones. Experts theorize that yawning may also directly influence brain activity by prompting movements of brain fluid away from a resting network and into a more active state. WebWidely considered to be one of the founders of modern chronobiology, British-American biologist Colin Pittendrigh introduced some of the first formal models that describe how circadian rhythms entrain, or synchronize, to local light-dark cycles.In his lab, Pittendrigh and his colleagues focused many of their studies on the ever-popular fruit fly, Drosophila.
