Thinking about death can cause us to feel a sort of existential angst that isn't attributable to a specific source. Now, new research suggests that acetaminophen, an over-the-counter pain medication, may help to reduce this existential pain. http://medicalxpress.com/news/2013-04-experiencing-existential-dread-tylenol.html Psychology & Psychiatry Tue, 16 Apr 2013 09:25:57 EST news285323140 A new therapy could help suppress tremors in people with Parkinson's disease, an Oxford University study suggests. http://medicalxpress.com/news/2013-02-therapy-electricity-cancel-parkinson-tremors.html Parkinson's & Movement disorders Mon, 18 Feb 2013 04:08:08 EST news280382872 (Medical Xpress)—Neuroscience researchers at Trinity College Dublin have opened a new avenue for research on how the brain enables us to make decisions about our environment. By observing the gradual formation of a decision in brain activity before the particular decision was actually reported, the findings also have the potential to contribute to improved understanding and diagnosis of numerous brain disorders that are associated with impaired perceptual decision making. The discovery was recently published in Nature Neuroscience. http://medicalxpress.com/news/2012-12-brain-decisions.html Neuroscience Tue, 04 Dec 2012 06:21:56 EST news273824505 Short-term alcohol intake can increase the activity of functional connections across the human brain when it is at rest, according to research published Oct 31 in the open access journal PLOS ONE by Panagiotis Bamidis and colleagues from the Aristotle University of Thessaloniki, Greece. http://medicalxpress.com/news/2012-10-alcohol-resting-brain-social-drinkers.html Neuroscience Wed, 31 Oct 2012 20:21:20 EST news270933603 (Medical Xpress) -- Scientists have discovered a biological marker that may help to identify which depressed patients will respond to an experimental, rapid-acting antidepressant. The brain signal, detectable by noninvasive imaging, also holds clues to the agent’s underlying mechanism, which are vital for drug development, say National Institutes of Health researchers. http://medicalxpress.com/news/2012-08-brain-id-fast-acting-antidepressant.html Neuroscience Mon, 06 Aug 2012 08:26:28 EST news263460346 A novel mechanism for anxiety behaviors, including a previously unrecognized inhibitory brain signal, may inspire new strategies for treating psychiatric disorders, University of Chicago researchers report. http://medicalxpress.com/news/2012-05-mystery-gene-reveals-mechanism-anxiety.html Genetics Tue, 15 May 2012 12:00:01 EST news256299869 (AP) -- Call it the alter-ego of super-sizing. Researchers infiltrated a fast-food Chinese restaurant and found up to a third of diners jumped at the offer of a half-size of the usual heaping pile of rice or noodles - even when the smaller amount cost the same. http://medicalxpress.com/news/2012-02-trimming-super-size-half-orders-plate.html Health Mon, 13 Feb 2012 15:20:01 EST news248367593 (Medical Xpress) -- At UCLA's Laboratory of Integrative Neuroimaging Technology, researchers use functional MRI brain scans to observe brain signal changes that take place during mental activity. They then employ computerized machine learning (ML) methods to study these patterns and identify the cognitive state — or sometimes the thought process — of human subjects. The technique is called "brain reading" or "brain decoding."   http://medicalxpress.com/news/2011-12-neuroscientists-crucial-advances-brain.html Neuroscience Wed, 21 Dec 2011 06:50:01 EST news243670589
