18/10/2017A new study into the genetics underlying restless legs syndrome has identified 13 previously-unknown genetic risk variants, while helping inform potential new treatment options for the condition.
13/10/2017A study has given new insights into how sleep contributes to brain plasticity – the ability for our brain to change and reorganise itself – and could pave the way for new ways to help people with learning and memory disorders.
11/10/2017Rice, UTHealth researchers use light-sensitive molecules to track proteins critical to cell signaling.
10/10/2017Study suggests role of inflammation in brain disease is complicated.
09/10/2017University of Tsukuba researcher discovers why we have the tendency to fall asleep in the absence of motivating stimuli, when bored.
29/09/2017An international team of scientists led by Dr. Carlo Vittorio Cannistraci, Junior Group Leader of the Biomedical Cybernetics lab at the BIOTEChnology Center TU Dresden, has developed a powerful computational method that can exploit the principles of brain-network self-organization.
27/09/2017A lack of sleep is associated with more absence and teens turn up jet lagged to school on Mondays, as shown in a doctoral thesis by sleep researcher Serena Bauducco, at Örebro University, Sweden.
26/09/2017Whether or not we consciously perceive the stimuli projected onto our retina is decided in our brain. A recent study by the University of Bonn shows how some signals dissipate along the processing path to conscious perception. This process begins at rather late stages of signal processing.
05/09/2017Gut microbes have been in the news a lot lately. Recent studies show they can influence human health, behavior, and certain neurological disorders, such as autism. But just how do they communicate with the brain?
04/09/2017New research reveals the mechanisms behind the effects of chronic stress and tiny inflammations in the brain on fatal gut failure. Hokkaido University researchers revealed that fatal gut failure in a multiple sclerosis (MS) mouse model, EAE, under chronic stress is caused by a newly discovered nerve pathway.
01/09/2017Stress, fatigue, and feeling like your memory is failing you. These are the symptoms of a growing group of patients studied as part of a thesis at Sahlgrenska Academy. Result – They may need help, but they are rarely entering the initial stages of dementia.
25/08/2017The ability to distinguish between different kinds of caresses on the skin already exists at a very early age. This is evident from a study by the Sahlgrenska Academy, in which the blood supply in brains of infants 6 to 10 weeks old was investigated.
16/08/2017Human-computer interactions, such as playing video games, can have a negative impact on the brain, says a new Canadian study published in Molecular Psychiatry. For over 10 years, scientists have told us that action video game players exhibit better visual attention, motor control abilities and short-term memory. But, could these benefits come at a cost?
02/08/2017A molecule produced by insulating glial cells facilitates the functional wiring of brain cells involved in motor coordination.
31/07/2017The push to develop treatments for Alzheimer's disease has been a promising and disappointing endeavor over the past two decades, yielding a greater understanding of the disease yet still failing to generate successful new drugs.
24/07/2017Numerous studies have shown that physical exercise seems beneficial in the prevention of cognitive impairment and dementia in old age. Now researchers at Goethe University Frankfurt have explored in one of the first studies worldwide how exercise affects brain metabolism.
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.
