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.
30/11/2016Some people claim to experience pain just watching something painful to happen. This is true especially of people suffering from complex regional pain syndrome (CRPS), a disabling chronic pain disorder in a limb. In CPRS patients, both own movements and just observing other persons' movements may aggravate the pain.
28/11/2016Researchers at Children's Hospital Los Angeles (CHLA) have conducted the first study of its kind, using proton magnetic resonance spectroscopy (MRS) to look at brain regions in both adults and children who stutter.
22/11/2016We humans walk with our feet. This is true, but not entirely. Walking, as part of locomotion, is a coordinated whole-body movement that involves both the arms and legs. Researchers at the Biozentrum of the University of Basel and the Friedrich Miescher Institute for Biomedical Research have identified different subpopulations of neurons in the spinal cord with long projections.
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.
15/11/2016Researchers from MIT and Harvard Medical School have developed a biocompatible and highly stretchable optical fiber made from hydrogel — an elastic, rubbery material composed mostly of water. The fiber, which is as bendable as a rope of licorice, may one day be implanted in the body to deliver therapeutic pulses of light or light up at the first sign of disease.
09/11/2016Findings published this week in the Journal of Public Health reveal that both younger and older Canadian adults who engage in regular physical activity, consume more fruits and vegetables and are normal weight or overweight have overall better cognitive functioning.
31/10/2016Research investigating how DNA from a virus millions of years old may affect the development of nerve tumours, has been awarded funding.
31/10/2016The distinct structures of toxic protein aggregates that form in degenerating brains determine which type of dementia will occur, which regions of brain will be affected, and how quickly the disease will spread, according to a study from the Peter O’Donnell Jr. Brain Institute.
28/10/2016International experts are concerned about WHO moves in classification process. "The medical rationale for stroke being a disease of the brain is overwhelming." This is the key message of an urgent appeal launched by leading neurology experts in The Lancet.
05/10/2016Diseases of the central nervous system (CNS) may manifest as pathological changes in the retina of the eye. Research from the University of Eastern Finland (UEF) shows that retinal changes may be detected earlier than brain changes. Findings from mouse models suggest that eye examination could be used as a noninvasive screening tool for human brain diseases.
04/10/2016A team of researchers from the University of Zurich has studied the effects of acute sleep deprivation in children for the first time. They discovered that the brain in five to 12-year-olds responds differently to sleep deprivation compared to adults.
19/09/2016Jumping genes, so-called transposons, reproduce as parasites in the genome. This selfish behavior can be an evolutionary advantage for the organism or harm it. There is still a debate about the factors controlling the activity of transposons.
16/09/2016The following factors facilitate the formation of putatively toxic structures in the neuronal nuclei of Alzheimer's patients. Spherical structures in the nucleus of nerve cells, so-called nuclear spheres, are suspected to trigger Alzheimer's disease.
14/09/2016Researchers in Singapore have developed a new protein that can alter DNA in living cells with much higher precision than current methods.
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.
