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
2014-01-03 17:55:35

[ 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...

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...

Vegetative Patients Recognize Loved ones
2013-12-17 08:29:25

redOrbit Staff & Wire Reports - Your Universe Online Patients in a vegetative state may be able to recognize photographs of their family and friends, according to a new study published this month in the journal PLOS ONE. Although patients in a vegetative state are awake, can breathe on their own, and appear to go in and out of sleep, they do not respond to what is happening around them, and exhibit no signs of conscious awareness. Since communicating with these patients is...

German researchers gain new insights into the functioning of the brain While the human brain is in a resting state, patterns of neuronal activity which are associated to specific memories may spontaneously reappear. Such recurrences contribute to memory consolidation – i.e. to the stabilization of memory contents. Scientists of the DZNE and the University of Bonn are reporting these findings in the current issue of The Journal of Neuroscience. The researchers headed by Nikolai Axmacher...

Training Dogs To To Undergo Successful Functional Magnetic Resonance Imaging
2013-12-05 06:23:55

Emory University After capturing the first brain images of two alert, unrestrained dogs last year, researchers at Emory University have confirmed their methods and results by replicating them in an experiment involving 13 dogs. The research, published by the Public Library of Science One (PLOS One), showed that most of the dogs had a positive response in the caudate region of the brain when given a hand signal indicating they would receive a food treat, as compared to a different hand...

Anxiety And Social Phobias Made Worse By Missing 'Brake' In The Brain
2013-12-05 05:20:13

redOrbit Staff & Wire Reports - Your Universe Online A team led by researchers from the Medical University of Vienna has discovered one possible source of anxiety disorders and severe phobias – a missing inhibitory connection or “brake” in the brain. When experienced at a manageable level, fear can make people alert and help protect them against danger, it can also disrupt an individual’s sensory perception and reduce happiness when it becomes disproportionate. Now the...

Awareness May Be Possible When In A Vegetative State
2013-11-03 04:35:27

Alan McStravick for redOrbit.com - Your Universe Online The concept of being in a coma or vegetative state is only made the more frightening when you add in the possibility that while lying there, hooked to medical equipment and having one’s life prolonged by a support system, a cognizance of one’s surroundings damns you to a waking nightmare of unknown duration. Thankfully, those in a vegetative state are spared this scenario. Or are they? According to a new study, a patient who...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
