Weizmann Institute scientists discover that spontaneously emerging brain activity patterns preserve traces of previous cognitive activity What if experts could dig into the brain, like archaeologists, and uncover the history of past experiences? This ability might reveal what makes each of us a unique individual, and it could enable the objective diagnosis of a wide range of neuropsychological diseases. New research at the Weizmann Institute hints that such a scenario is within the realm...

Carbon Nanotube Harpoon Used to Catch Individual Brain-cell Signals
2013-06-20 11:33:48

Duke University Neuroscientists may soon be modern-day harpooners, snaring individual brain-cell signals instead of whales with tiny spears made of carbon nanotubes. The new brain cell spear is a millimeter long, only a few nanometers wide and harnesses the superior electromechanical properties of carbon nanotubes to capture electrical signals from individual neurons. "To our knowledge, this is the first time scientists have used carbon nanotubes to record signals from individual...

Fiber-optic Pen Used To See Inside Brains Of Children With Learning Disabilities
2013-06-18 13:09:41

University of Washington For less than $100, University of Washington researchers have designed a computer-interfaced drawing pad that helps scientists see inside the brains of children with learning disabilities while they read and write. The device and research using it to study the brain patterns of children will be presented June 18 at the Organization for Human Brain Mapping meeting in Seattle. A paper describing the tool, developed by the UW´s Center on Human Development and...

New Imaging Technique Could Help Speed Up Research For MS

University of British Columbia Researchers at the University of British Columbia have developed a new magnetic resonance imaging (MRI) technique that detects the telltale signs of multiple sclerosis in finer detail than ever before — providing a more powerful tool for evaluating new treatments. The technique analyzes the frequency of electro-magnetic waves collected by an MRI scanner, instead of the size of those waves. Although analyzing the number of waves per second had long...

Elena Prieto-Azkarate, a graduate in Telecommunications Engineering at the NUP/UPNA-Public University of Navarre and member of the Nuclear Medicine Service of the University College Hospital of Navarre, has implemented 12 algorithms to process medical images produced by means of PET (Positron Emission Tomography). As she points out in her PhD thesis, read at the NUP/UPNA, the results obtained are highly promising and this technique could be very useful indeed.She has also developed a graphics...

Study reveals new hybrid molecular imaging system is as good as PET/CT gold standard for restaging patients with metastatic prostate cancer When prostate cancer makes a comeback, it becomes increasingly important to have exceptional imaging available to find all possible regions where cancer has spread to other parts of the body, or metastasized, in order to plan the best possible treatment. A relatively new imaging system that simultaneously combines positron emission tomography and...

Parallel imaging improves risk stratification and patient management and hints toward potential benefits of simultaneous PET/MR For patients with advanced breast cancer, positron emission tomography (PET) and magnetic resonance (MR) imaging can improve quality of life and survival by providing physicians with information on the effectiveness of chemotherapy prior to surgery, say researchers presenting at the 2013 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging....

Healthy test subjects with amyloid plaque were also found to have hypometabolism indicating a potential Alzheimer´s precursor Alzheimer´s disease has been linked in many studies to amyloid plaque buildup in the brain, but new research is finding a common thread between amyloid burden and lower energy levels, or metabolism, of neurons in certain areas of the brain associated with Alzheimer´s disease–even for people with no sign of cognitive decline. This is a new...

High resolution, low dose imaging modality could diversify options for clinicians The Society of Nuclear Medicine and Molecular Imaging´s 2013 Annual Meetingmarks the unveiling of the successful application of a new preclinical hybrid molecular imaging system–single photon emission tomography and magnetic resonance (SPECT/MR)–which has exceptional molecular imaging capabilities in terms of potential preclinical and clinical applications, technological advancement at a...

Magnetic resonance-based wearable technology accounts for patient movement for clearer data reconstruction and fewer imaging artifacts One of the biggest hurdles of hybrid positron emission tomography and magnetic resonance (PET/MR) imaging is the prevalence of motion artifacts–blurring and ghostly visual anomalies caused by patient motion on the table during imaging. An MR technology has now been designed for PET/MR that employs tiny radiofrequency solenoids–metal coils...
