A prime example of this is the timing of the sleep/wake cycle, which is synchronized by the effects of light on the circadian pacemaker in the hypothalamus. http://www.huliq.com/44832/mammalian-eye-detects-light-non-visual-phenomena#comments Science circadian cells hypothalamus light Fri, 14 Dec 2007 13:25:16 -0600 harminka 44832 at http://www.huliq.com http://www.huliq.com/17697/circadian-neuronal-network-is-seasonal-timing-device A Brandeis University study published in Cell this week shows for the first time experimentally that the circadian cells in fruit flies function as a network that enables the insects to adapt their behavior according to seasonal changes. This discovery leads the way to understanding how mammals, and presumably humans, adjust physiology and behavior to environmental changes such as short winter days and long summer ones. http://www.huliq.com/17697/circadian-neuronal-network-is-seasonal-timing-device#comments Science circadian cells Drosophila fruit flies insects behavior mammals Seasonal changes Fri, 06 Apr 2007 10:43:45 -0500 harminka 17697 at http://www.huliq.com
