This is known as the circadian rhythm and, in mammals, it is controlled by signaling in a region of the brain called the suprachiasmatic nucleus (SCN). The SCN regulates a number of functions, including hormonal secretion, metabolism, brain activity and sleep. http://medicalxpress.com/news/2013-02-neurotransmitter-serotonin-shown-link-sleepwake.html Neuroscience Fri, 22 Feb 2013 08:29:41 EST news280744175 New understanding can lead to srategies for dealing with neurodegenerative diseases A new understanding of what takes place on the cellular level during the development of neurodegenerative diseases, such as Parkinson's, Alzheimer's, ALS and Huntington's diseases, offers promise towards possible new strategies for combating such diseases, say Hebrew University of Jerusalem researchers. http://medicalxpress.com/news/2012-12-srategies-neurodegenerative-diseases.html Medical research Thu, 06 Dec 2012 10:44:36 EST news274013065 Glutamate neurotransmission system may be involved with depression risk Researchers using a new approach to identifying genes associated with depression have found that variants in a group of genes involved in transmission of signals by the neurotransmitter glutamate appear to increase the risk of depression. The report published in the journal Translational Psychiatry suggests that drugs targeting the glutamate system may help improve the limited success of treatment with current antidepressant drugs. http://medicalxpress.com/news/2012-11-glutamate-neurotransmission-involved-depression.html Psychology & Psychiatry Tue, 13 Nov 2012 14:00:38 EST news272037627 More than a sign of sleepiness, yawning may cool the brain Though considered a mark of boredom or fatigue, yawning might also be a trait of the hot-headed.
