Recovery depends on the exchange of information between the brain hemispheres The structure of the corpus callosum, a thick band of nerve fibres that connects the two halves of the brain with each other and in this way enables the rapid exchange of information between the left and right hemispheres, plays an important role in the regaining of motor skills following a stroke. A study currently published in the journal Human Brain Mapping has shown that in stroke patients with particularly...

(Ivanhoe Newswire) -- Everyone is told to exercise, exercise, exercise - it improves your health. Now, researchers from Georgetown University Medical Center say that it may also have benefits for a serious medical condition. Presented at the society of Neuroscience's annual meeting - Neuroscience 2011, the study showed that six weeks of exercise substantially improved memory retention and pain control for fibromyalgia patients who were no longer being treated with medications....

John DeLuca, PhD, Vice President for Research at Kessler Foundation presented findings on the use of a behavioral technique for cognitive rehabilitation in people with multiple sclerosis (MS).  Lead investigator was Nancy Chiaravalloti, PhD, director of the Neuropsychology & Neuroscience Laboratory at Kessler Foundation.  The presentation on modified Story Memory Technique was made on October 21, 2011 in Amsterdam at the 5th Joint Triennial Congress of the European and Americas...

Georgetown researchers use fMRI to correlate exercise with memory performance changes in the brain Areas of the brain responsible for pain processing and cognitive performance changed in fibromyalgia patients who exercised following a medication holiday, say researchers from Georgetown University Medical Center. They say the changes indicate brain functioning is more streamlined after an exercise intervention because less of the brain´s resources is devoted to processing bothersome...

Brain imaging experiments uncouple two apparently intimately connected mental processes In everyday life, attention and awareness appear tightly interwoven. Attending to the scissors on the right side of your desk, you become aware of their attributes, for example the red handles. Vice versa, the red handles could attract your attention to the scissors. However, a number of behavioural observations have recently led scientists to postulate that attention and awareness are fundamentally...

Image 1 - So That's What Dreams Are Made Of
2011-10-28 10:54:01

Scientists measure dream content for the first time and find that dreams activate the brain in a similar way to real actions. The ability to dream is a fascinating aspect of the human mind. However, how the images and emotions that we experience so intensively when we dream form in our heads remains a mystery. Up to now it has not been possible to measure dream content. Max Planck scientists working with colleagues from the Charité hospital in Berlin have now succeeded, for...

Haxby found that the brain's responses to movies reveal a detailed code that is the same for all individuals A team of neuroscientists at Dartmouth College has shown that different individuals' brains use the same, common neural code to recognize complex visual images. The paper, "A common, high-dimensional model of the neural representational space in human ventral temporal cortex," is in the October 20, 2011, issue of the journal, Neuron. The lead author of the paper is James Haxby,...

-A low level of response (LR) to alcohol reflects at least in part a low brain response to alcohol and carries significant risk for the later development of alcoholism. -This study used functional magnetic resonance imaging (fMRI) to examine brain activation in individuals with low and high LRs to alcohol while they performed a cognitive task. -Significant differences detected in brain activation may contribute to the inability by individuals with a low LR to recognize modest levels of...

(Ivanhoe Newswire) — Some people always view everything with the glass half full. Even if you´re a fan of the Browns and they keep losing, you still think that next week will be the week that they´ll turn it all around. So why, in the face of obvious evidence suggesting the contrary, do some people remain so optimistic about the future? According to researchers at the Wellcome Trust Centre for Neuroimaging at UCL (University College London) people who are very optimistic...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
