For Brain Cancer - A Thought-Provoking New Therapeutic Target? published
Fri, 03 Feb 2012 00:00:00 PST
Glioblastoma multiforme (GBM) is the most common of all malignant brain tumors that originate in the brain. Patients with GBM have a poor prognosis because it is a highly aggressive form of cancer that is commonly resistant to current therapies. New therapeutic approaches are therefore much needed...
Noise Exposure Can Cause Long-Lasting Changes To Sensory Pathways; Touch-Sensing Nerve Cells May Lead To Future Tinnitus Treatments published
Fri, 03 Feb 2012 00:00:00 PST
We all know that it can take a little while for our hearing to bounce back after listening to our iPods too loud or attending a raucous concert. But new research at the University of Michigan Health System suggests over-exposure to noise can actually cause more lasting changes to our auditory circuitry - changes that may lead to tinnitus, commonly known as ringing in the ears...
Investigating The Neural Basis Of Prosopagnosia published
Fri, 03 Feb 2012 00:00:00 PST
For Bradley Duchaine, there is definitely more than meets the eye where faces are concerned. With colleagues at Birkbeck College in the University of London, he is investigating the process of facial recognition, seeking to understand the complexity of what is actually taking place in the brain when one person looks at another...
Dyslexia-Linked Genetic Variant Decreases Midline Crossing Of Auditory Pathways published
Fri, 03 Feb 2012 00:00:00 PST
Finnish scientists have found that a rare dyslexia-linked genetic variant of the ROBO1 gene decreases normal crossing of auditory pathways in the human brain. The weaker the expression of the gene is, the more abnormal is the midline crossing. The results link, for the first time, a dyslexia-susceptibility gene to a specific sensory function of the human brain...
An Explanation For Why The Brain May Become More Reluctant To Function As We Grow Older published
Fri, 03 Feb 2012 00:00:00 PST
New findings, led by neuroscientists at the University of Bristol and published this week in the journal Neurobiology of Aging, reveal a novel mechanism through which the brain may become more reluctant to function as we grow older. It is not fully understood why the brain's cognitive functions such as memory and speech decline as we age...
Abnormal Brain Structure In Both Siblings - Addiction Only Affects One published
Thu, 02 Feb 2012 15:00:00 PST
A study conducted by Dr. Karen Ersche, Department of Psychiatry, University of Cambridge, England, and published in Science, reveals that one sibling who is addicted to drugs, and the other who is not, have similar brain abnormalities. These abnormalities come from an area of the brain that is vital for aiding people in exhibiting self control...
Are CT Scans For Dizziness In ER Cost-Effective? published
Thu, 02 Feb 2012 10:00:00 PST
Henry Ford Hospital researchers have found that conducting CT scans in the emergency department (ED) for individuals experiencing dizziness may not be cost effective. The researchers discovered that less than 1% of CT scans carried out in the ED showed a more serious underlying cause for dizziness (stroke or intracranial bleeding), which required intervention...
Scientists Have Now Discovered How Different Brain Regions Cooperate During Short-Term Memory published
Thu, 02 Feb 2012 01:00:00 PST
Holding information within one's memory for a short while is a seemingly simple and everyday task. We use our short-term memory when remembering a new telephone number if there is nothing to write at hand, or to find the beautiful dress inside the store that we were just admiring in the shopping window...
Fatal Strokes May Be Predicted By Earlier Severe, Rapid Memory Loss published
Thu, 02 Feb 2012 01:00:00 PST
Severe, rapid memory loss may be linked to - and could predict - a future deadly stroke, according to research presented at the American Stroke Association's International Stroke Conference 2012. Researchers found that people who died after stroke had more severe memory loss in the years before stroke compared to people who survived stroke or people who didn't have a stroke...
The Development Of Parkinson's Cells Visualized By Researchers published
Thu, 02 Feb 2012 00:00:00 PST
In the US alone, at least 500,000 people suffer from Parkinson's disease, a neurological disorder that affects a person's ability to control his or her movement. New technology from the University of Bonn in Germany lets researchers observe the development of the brain cells responsible for the disease...

Researchers Rewrite Textbook On Location Of Brain's Speech Processing Center published
Wed, 01 Feb 2012 01:00:00 PST
Scientists have long believed that human speech is processed towards the back of the brain's cerebral cortex, behind auditory cortex where all sounds are received - a place famously known as Wernicke's area after the German neurologist who proposed this site in the late 1800s based on his study of brain injuries and strokes...
Decoding Brain Waves Could Lead To Communication With Patients Unable To Speak published
Wed, 01 Feb 2012 01:00:00 PST
Neuroscientists may one day be able to eavesdrop on the constant, internal monologs that run through our minds, or hear the imagined speech of a stroke or a locked-in patient with inability to speak, according to researchers at the University of California, Berkeley...
Association Between Heart Failure, Loss Of Brain Cells And A Decline In Mental Processes published
Wed, 01 Feb 2012 01:00:00 PST
Australian researchers have found evidence that heart failure is associated with a decline in people's mental processes and a loss of grey matter in the brain. These changes can make it more difficult for heart failure (HF) patients to remember and carry out instructions such as taking the correct medication at the right times...
Scientists Transform Skin Cells Direct To Brain Cells, Bypassing Stem Cell Stage published

Bypassing the stem cell stage, researchers at the Stanford University School of Medicine in California converted mouse skin cells directly into neural precursor cells, the cells that go on to form the three main types of cell in the brain and nervous system. They write about their findings in the 30 January early online issue of the Proceedings of the National Academy of Sciences...
Defects In The Packaging Of DNA In Malignant Brain Tumors published
Wed, 01 Feb 2012 00:00:00 PST
Glioblastomas grow extremely aggressively into healthy brain tissue and, moreover, are highly resistant to radiation therapy and chemotherapy. Therefore, they are regarded as the most malignant type of brain tumor. Currently available treatment methods are frequently not very effective against this type of cancer...
