03/01/2019The National Science Foundation BIGDATA program awarded $1,200,000 to a research team led by the University of Pittsburgh Swanson School of Engineering to study the big brain data for complex brain disorders and design new algorithms that address computational challenges in multi-site collaborative data mining.
20/12/2018In mammals, generation of new neurons (neurogenesis) is mainly limited to early childhood and occurs in adulthood only in a few regions of the forebrain. One such exception is olfactory neurons, which develop from stem cells via several intermediate stages.
17/12/2018Pain is a negative feeling that we want to get rid of as soon as possible. In order to protect our bodies, we react for example by withdrawing the hand. This action is usually understood as the consequence of the perception of pain.
13/12/2018Researchers at Stanford University, Palo Alto, California, have created a noninvasive technology that detects when nerve cells fire based on changes in shape. The method could be used to observe nerve activity in light-accessible parts of the body, such as the eye, which would allow physicians to quantitatively monitor visual function at the cellular level.
11/12/2018In a study published in Neuron, Emilie Macé from Botond Roska’s group and collaborators demonstrate how functional ultrasound imaging can yield high-resolution, brain-wide activity maps of mice for specific behaviors. The non-invasive technology has promising applications for ophthalmologic, neurologic and psychiatric diseases.
10/12/2018So far, lower arm prostheses often only functioned as a cosmetic disguise to conceal the missing body part. While newer models help the wearer with grip patterns, every hand grip has to be readjusted and newly activated. There is still no prosthetic device that is easy to control and allows a flexible response to objects the wearer is grasping.
06/12/2018The wonders of graphene are numerous. Now, the "supermaterial" may one day be used to test for amyotrophic lateral sclerosis, or ALS – a progressive, neurodegenerative disease which is diagnosed mostly by ruling out other disorders, according to new research from the University of Illinois at Chicago published in ACS Applied Materials & Interfaces.
03/12/2018The treatment for many neurological and mental disorders is far from being an easy feat. Drug therapies always require accurate medication adjustments, while brain surgeries have the potential for risks and complications. Non-invasive brain stimulation takes a different approach: magnetic fields and electric current change the activities in the brain - without putting the patient at risk.
03/12/2018According to estimates, every third person in the world suffers from chronic pain. The most common discomforts include back pain, headaches, and nerve pain. For many sufferers, the pain is so severe that it impacts their job, social life or mind. The pain has its own clinical significance and must be treated – with electric current for example.
22/11/2018Every year between 250.000 and 500.000 people suffer a spinal cord injury, MoreGrasp is intended to make their lives easier. The project aims to restore the lost gripping function in people with high paraplegia. Researchers at Graz University of Technology have developed a neuroprosthesis that is currently undergoing a feasibility study.
05/11/2018Gulf War veterans with unexplained illnesses that cause fatigue, headaches, respiratory disorders and memory problems can improve their balance with a device developed by Rutgers University researchers.
24/10/2018Neuroprosthetics - implants containing multi-contact electrodes that can substitute certain nerve functionalities - have the potential to work wonders. They may be able to restore amputees' sense of touch, help the paralyzed walk again by stimulating their spinal cords and silence the nerve activity of people suffering from chronic pain.
23/10/2018The entrainment of theta brain waves with a commercially available device not only enhances theta wave activity, but also boosts memory performance. That's according to new research from the Center for Neuroscience at the University of California, Davis, published recently in the journal Cognitive Neuroscience.
01/08/2018Big Data is often likened to finding the proverbial needle in a haystack: Large volumes of data contain patterns that hold the answer to a particular question. The trick is to gather meaningful data and identify patterns. The i-PROGNOSIS research project shows how smart devices and an app team up to automatically collect data without disturbing the user.
08/03/2018Automation makes work life easier in many ways but is it also a solution for analyzing medical images? Is a computer actually reliable enough to assist in the medical decision making process? Researchers in Landshut examine how machine learning algorithms can work more reliably and support radiologists.
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.
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.
