22/05/2017Is what you're looking at an object, a face, or a tree? When processing visual input, our brain uses different areas to recognize faces, body parts, scenes, and objects. Scientists at KU Leuven (University of Leuven), Belgium, have now shown that people who were born blind use a 'brain map' with a very similar layout to distinguish between these same categories.
15/05/2017Sleep is of absolute necessity for us humans, although if one falls asleep all of a sudden while being awoken, it would cause a big trouble. The brain is equipped with sleep mechanism and wakefulness mechanism, which are regulated to be on or off in an adequate manner.
11/05/2017It is not often that a fall saves someone's life. Helen Powell, 74, says that was the case for her. A computerized tomography scan that followed her fall revealed a cancerous brain tumor that led her to Mayo Clinic and surgery using first-in-the-world technology. Brain magnetic resonance elastography (MRE) imaging, showed the precise firmness of her tumor.
10/05/2017A computer-driven automated drill, similar to those used to machine auto parts, could play a pivotal role in future surgical procedures. The new machine can make one type of complex cranial surgery 50 times faster than standard procedures, decreasing from two hours to two and a half minutes.
28/04/2017Traditional toxicological investigations performed on animals (in vivo) are expensive, time-consuming and may cause animal suffering. But research from Umeå University demonstrates that a neuronal cell model, derived from mouse, can be used to evaluate the neurotoxic effect of chemicals.
24/04/2017A new study has made a major new discovery towards finding the cause of multiple sclerosis (MS), potentially paving the way for research to investigate new treatments. Ahead of MS Awareness Week an international team has discovered a new cellular mechanism that may cause the disease, and a potential hallmark that may be a target for future treatment of the autoimmune disorder.
17/04/2017A team led by engineers at the University of California San Diego has developed nanowires that can record the electrical activity of neurons in fine detail. The new nanowire technology could one day serve as a platform to screen drugs for neurological diseases and could enable researchers to better understand how single cells communicate in large neuronal networks.
12/04/2017Researchers at the University of Liverpool have identified the basis for how a single gene mutation can cause a rare neurological movement disorder known as dystonia. It can result from an injury or can be an inherited disorder in which patients progressively develop from childhood uncontrollable muscle contractions leading to repetitive movements and awkward and painful postures.
10/04/2017A surgical technique that sends electrical impulses to a specific area of the brain reduces the "tics," or involuntary movements and vocal outbursts, experienced by young adults with severe cases of Tourette syndrome, according to a new study led by investigators from NYU Langone Medical Center.
22/03/2017Tea drinking reduces the risk of cognitive impairment in older persons by 50 per cent and as much as 86 per cent for those who are genetically at risk of Alzheimer's.
22/03/2017A study led by Indiana University School of Medicine researchers demonstrates how electroacupuncture triggers a neurological mechanism that can help promote tissue repair and relieve injury-induced pain.
20/03/2017A team of engineers at the University of California San Diego and La Jolla-based startup Nanovision Biosciences Inc. have developed the nanotechnology and wireless electronics for a new type of retinal prosthesis that brings research a step closer to restoring the ability of neurons in the retina to respond to light.
09/03/2017Gentle sound stimulation - such as the rush of a waterfall - synchronized to the rhythm of brain waves significantly enhanced deep sleep in older adults and improved their ability to recall words, reports a new Northwestern Medicine study.
08/03/2017Researchers have identified a new mechanism by which inflammation can spread throughout the brain after injury. This mechanism may explain the widespread and long-lasting inflammation that occurs after traumatic brain injury, and may play a role in other neurodegenerative diseases.
07/03/2017A type of functional brain training known as neurofeedback shows promise in reducing symptoms of chemotherapy-induced nerve damage, or neuropathy, in cancer survivors, according to a study by researchers at The University of Texas MD Anderson Cancer Center. The pilot study, published in the journal "Cancer", is the largest, to date, to determine the benefits of neurofeedback in cancer survivors.
01/03/2017For the first time ever, a single flexible fiber no bigger than a human hair has successfully delivered a combination of optical, electrical, and chemical signals back and forth into the brain, putting into practice an idea first proposed two years ago.
22/02/2017For all the improvements in computer technology over the years, we still struggle to recreate the low-energy, elegant processing of the human brain. Now, researchers at Stanford University and Sandia National Laboratories have made an advance that could help computers mimic one piece of the brain's efficient design - an artificial version of the space over which neurons communicate, a synapse.
08/12/2016Watching millions of neurons in the brain interacting with each other – for a long time this was possible only to a limited extent. The current techniques can visualize only superficial layers or the imaging they use is too slow. But now, Prof Daniel Razansky and his team have found a new method to visualize the brain activity – by using optoacoustics.
22/11/2016It happens about 1,800 times per year: after a sporting or traffic-related accident, a person’s spinal cord is injured to where nerve tracts are severed and he/she becomes paralyzed. Researchers now want to develop software that measures the brain signals of paralyzed patients and sends out electrical impulses via a system to stimulate muscles, causing them to move again.
22/07/2016Millions of people all over the world suffer from partial blindness – caused by glaucoma, a stroke or traumatic brain injury. For years, the loss of vision was deemed irreversible. But now a new treatment makes it possible to improve eyesight and vision.
01/12/2015Multiple sclerosis apparently can strike anyone - regardless of age, family history, lifestyle or gender. Yet why then does it not strike everyone? Genetic and environmental factors appear not to be the only reason whether it develops or not. The countless microorganisms that colonize our intestinal tract could also be involved in this.
01/07/2015When measuring myocardial activity, it is important for the skin to always stay moist under the electrodes of the ECG. Only then can data be consistently transferred. Athletes have an easier time with this: they are used to sweating. This is a lot harder for older patients.
08/05/2015The bowel is surrounded by a dense plexus of nervous tissue that presents problems for surgeons. On the one hand, it is difficult to distinguish from the surrounding tissue; while on the other hand, sometimes portions of it need to be removed when parts of the colon are removed. Yet injuring these nerves can result in permanent damage.
01/12/2014How does a physician handle a patient, who wants to die and what rights do I actually have as a patient? Legal practitioners do not automatically answer these and other questions. We talked about this subject with MD-PhD Ralf Jox from the Institute of Ethics, History and Theory of Medicine at the Ludwig Maximilians University of Munich, Germany.
01/09/2014The public only notices diseases when celebrities become patients: in the spring of 2014, Formula One driver Michael Schumacher fell into a coma for several months as the result of a head injury caused by a skiing accident. These types of accidents show how delicate the brain responds to injuries. Brain stimulation could possibly support the rehabilitation of vegetative patients.
01/07/2014In patients with Parkinson's, neural cells in the brain die off that produce the neurotransmitter dopamine. Certain physical symptoms that can indicate the disease follow years later. But a reliable diagnosis can only be made through examination of the brain after the patient's death, and not during his lifetime.
