17/10/2018The human brain contains about 90 billion neurons, Stephanie Jones, an associate professor of neuroscience at Brown University, doesn't let that staggering number faze her. In fact, she just released a user-friendly software tool that models the neural circuits in the outer layers of the brain, which produce the electrical activity monitored by noninvasive techniques.
25/09/2018How do we know if we're looking at three apples or four? Researchers at the Universities of Bonn and Tübingen are now one step closer to answering this question. They were able to demonstrate that some brain cells fire mainly for quantities of three, others for quantities of four and others for other quantities.
24/09/2018Babies born before their due date show better brain development when fed breast milk rather than formula, a study has found. Experts say that helping mothers to provide breast milk in the weeks after giving birth could improve long-term outcomes for children born pre-term.
13/09/2018Dopamine, a signaling molecule used throughout the brain, plays a major role in regulating our mood, as well as controlling movement. Many disorders, including Parkinson's disease, depression, and schizophrenia, are linked to dopamine deficiencies.

13/08/2018New research from a team led by Marshall University scientist W. Christopher Risher, Ph.D., reveals novel molecular insights into how multiple cell types drive the formation and maturation of brain circuits.
10/08/2018A space-exploring robot crashes on a distant planet. In order to gather the pieces of its damaged spaceship, it needs to build emotional rapport with the local alien inhabitants. The aliens speak a different language but their facial expressions are remarkably humanlike.
03/08/2018Building on their development of the first culture system to replicate fully the pathology behind Alzheimer's disease, a Massachusetts General Hospital (MGH) research team has now produced a system that includes neuroinflammation, the key biological response that leads to the death of brain cells.
02/08/2018The Allen Institute for Brain Science, a division of the Allen Institute, announced the launch of OpenScope, a project that will give researchers access to the Institute's "observatory of the mind" to study the activity of nerve cells in the visual cortex of the mouse. OpenScope was modeled after shared astronomy observatories that have been the seat of major findings about the physical universe.
01/08/2018A cutting-edge laboratory technique turns human stem cells into brain-like tissue now recapitulates human brain development. The new study from Case Western Reserve University School of Medicine was published in Nature Methods and shows how to grow brain "organoids"--self-organizing mini spheres that now contain all the major cell types found in the human cerebral cortex-in laboratory dishes.
01/08/2018Research conducted at the Wayne State University School of Medicine has helped confirm the effectiveness of a blood biomarker that can indicate if patients with a head injury can avoid a costly CT scan because the blood test results indicate no traumatic brain injury (TBI).
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.
31/07/2018Symptoms of Parkinson's disease include tremor, loss of smell and neuropsychiatric problems. However, many people are not diagnosed until their disease is well-advanced, which could limit their treatment options.
30/07/2018Recent studies show that 40 percent of Americans over the age of 85 have Alzheimer's disease, and that the disease begins 10 to 20 years before people show up at the doctor's office with memory problems.
25/07/2018A new study, presented at the Society of NeuroInterventional Surgery's (SNIS) 15th Annual Meeting, found that new stroke imaging technology could decrease delays in care by up to 60 minutes, giving patients a better chance at making a full recovery.
25/07/2018Recent studies show that 40 percent of Americans over the age of 85 have Alzheimer's disease, and that the disease begins 10 to 20 years before people show up at the doctor's office with memory problems.
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.
