A functional brain imaging technique known as positron emission tomography (PET) is a promising tool for determining which severely brain damaged individuals in vegetative states have the potential to recover consciousness, according to new research published in The Lancet. It is the first time that researchers have tested the diagnostic accuracy of functional brain imaging techniques in clinical practice. "Our findings suggest that PET imaging can reveal cognitive processes that aren't...

Long-term brain damage caused by stroke could be reduced by saving cells called pericytes that control blood flow in capillaries Long-term brain damage caused by stroke could be reduced by saving cells called pericytes that control blood flow in capillaries, reports a new study led by scientists from UCL (University College London). Until now, many scientists believed that blood flow within the brain was solely controlled by changes in the diameter of arterioles, blood vessels that...

Findings point to potential biomarkers for early detection of at-risk youth Researchers at the University of California, San Diego School of Medicine have discovered impaired neuronal activity in the parts of the brain associated with anticipatory functioning among occasional 18- to 24-year-old users of stimulant drugs, such as cocaine, amphetamines and prescription drugs such as Adderall. The brain differences, detected using functional magnetic resonance imaging (fMRI), are believed...

Researchers Identify Decision-making Center Of The Brain

April Reese Sorrow, University of Georgia Although choosing to do something because the perceived benefit outweighs the financial cost is something people do daily, little is known about what happens in the brain when a person makes these kinds of decisions. Studying how these cost-benefit decisions are made when choosing to consume alcohol, University of Georgia associate professor of psychology James MacKillop identified distinct profiles of brain activity that are present when making...

PHOENIX, March 7, 2014 /PRNewswire-USNewswire/ -- Researchers have demonstrated that conditioned pain modulation (CPM), a measure of the brain's ability to regulate pain, decreases activity in the human spinal cord as visible via functional magnetic resonance imaging (fMRI). "This study confirmed our hypothesis that CPM results in significant reductions in spinal dorsal horn activity in humans," said lead study author Ian Mackey, of Stanford University in Palo Alto, Calif. The...

Dogs Are Sensitive To Emotions
2014-02-21 04:24:32

[ Watch the Video: Dogs Know How You're Feeling ] redOrbit Staff & Wire Reports - Your Universe Online Humans can recognize the voices of their friends, get a mental image of them without actually seeing them, and determine their mood based on the tone of their voices because of a special region of their brain dedicated to these tasks. However, new research suggests we might not be the only mammal with these “voice areas.” Writing in the journal Current Biology, Attila Andics...

Head movement during fMRI may bias sampling toward subjects with lower cognitive ability Kessler Foundation researchers have shown that discarding data from subjects with multiple sclerosis (MS) who exhibit head movement during functional magnetic resonance imaging (fMRI) may bias sampling away from subjects with lower cognitive ability. The study was published in the January issue of Human Brain Mapping. (Wylie GR, Genova H, DeLuca J, Chiaravalloti N, Sumowski JF. Functional MRI movers...

Reading A Good Book Causes Physiological Changes In The Brain

[ Watch the Video: A Good Book For A Better Brain ] Brett Smith for redOrbit.com – Your Universe Online A great novel can whisk you away to a distant land or period far back in time, and a new study in the journal Brain Connectivity has found evidence that these novels can actually cause a physiological change in the brain that lasts for days. “Stories shape our lives and in some cases help define a person,” study author Gregory Berns, director of Emory’s Center for...

Do Brain Training Games Work
2014-01-02 14:28:29

[ Watch the Video: Brain Training - Does It Really Work? ] Brett Smith for redOrbit.com - Your Universe Online Apps for 'brain training' claim to use games or tasks as a way of enhancing cognitive abilities. However, a new study the Journal of Neuroscience suggests that these games may only improve a person’s capacity to perform the specific training task and lack evidence that this skill translates to other cognitive abilities. Study researchers looked specifically at a brain...

Alzheimer’s Disease Tracked From The Beginning
2013-12-23 04:42:10

redOrbit Staff & Wire Reports - Your Universe Online By combining high-resolution functional MRI (fMRI) imaging scans in Alzheimer’s disease patients with mouse models of the neurodegenerative condition, researchers from Columbia University Medical Center (CUMC) have gained new insights into how, where and why the disease starts and spreads. The study, which was published Sunday in the online edition of Nature Neuroscience, will help enhance the medical community’s understanding...
