Evidence for two asynchronous circadian systems of emotionality: theoretical aspects in comparative psychology.

From: The Journal of General Psychology | Date: October 1, 1995| Author: Poirel, Christian | Copyright information

This theoretical article is devoted to the chronobiological and chronopsychological foundations of emotion. Circadian fluctuations of experimentally induced emotionality have been reported from murine models (Poirel, 1982). Further research into rhythmometric investigations revealed that the temporal organization of emotional life expressed two oscillatory circadian systems. The circadian fluctuations that were rhythmometricaliy detected and compared expressed a noticeable phase concordance b...

Tune up your rhythms
Joe Weider's Muscle & Fitness ; All of us have at least one thing in common, whether we're hardgainers, slowgainers, A-shaped, T-shaped, train with free weights or machines: We wake up and go to sleep every day. Although we have some power over deciding when this occurs, our internal biological rhythms do most of the work. You

Overview of Circadian Rhythms.
Alcohol Research & Health ; The daily light-dark cycle governs rhythmic changes in the behavior and/or physiology of most species. Studies have found that these changes are governed by a biological clock, which in mammals is located in two brain areas called the suprachiasmatic nuclei. The circadian cycles established by this
Waking, and Blooming, in Rhythm
The Scientist ; 5-PRIME What are circadian rhythms? These timing systems dictate when plants will bloom, force people to fall asleep at their desks, urge birds to fly south, and influence a host of other activities. While circadian rhythms run on a 24-hour clock, others also exist, including tidal, lunar, and

Found: mouse circadian rhythm gene.

A few years ago, Takahashi and his colleagues randomly mutated genes in mice to disrupt their biological clock, the internal timepiece that creates daily cycles, or circadian rhythms, of activities such as sleeping, eating,

USA Today (Magazine) ; Circadian rhythms are the body's reaction to the alternation of light and dark and cues such as the timing of meals and sleep.This 24-hour light-dark circadian cycle is derived from the Latin circa ( about ) and dies ( dies ).

Plant Physiology ; The circadian clock is an intricate, even delicate, regulator of plant physiology, yet at least one of the selective pressures that drove its evolution is brutally simple. Plants must be exposed to sunlight for photosynthesis, and sunlight is not available continuously. Therefore, plants are stuck
