To better understand the link between the astronomical theory and the long ages assigned to the ice cores, it is necessary to discuss a topic that on the surface appears to have no connection whatsoever to the dating of ice cores: the chemistry of seafloor sediments.
A team of researchers led by Associate Professor Maria Kozhevnikov from the Department of Psychology at the National University of Singapore (NUS) Faculty of Arts and Social Sciences showed, for the first time, that it is possible for core body temperature to be controlled by the brain.
How our body maintains a constant temperature. Temperature receptors in the skin detect changes in the external temperature. They pass this information to the processing centre in the brain, called the hypothalamus. The processing centre also has temperature receptors to detect changes in the temperature of the blood.The processing centre automatically triggers changes to the effectors to ensure our body temperature remains constant, at 37Â°C. The effectors are sweat glands and muscles.he processing centre also has temperature receptors to detect changes in the temperature of the blood.
