Signaling Strength between nerve cells depends on size of connections
22/01/2021
The neocortex is the part of the brain that humans use to process sensory impressions, store memories, give instructions to the muscles, and plan for the future. These computational processes are possible because each nerve cell is a highly complex miniature computer that communicates with around 10,000 other neurons. This communication happens via special connections called synapses.

09/11/2020
An electroencephalogram (EEG) is a test that is used in cognitive research or to diagnose conditions such as epilepsy and sleep disorders. EEG electrode caps are somewhat difficult to wear, which is why they are only used in laboratories. One viable alternative are measuring devices made of printed electronics. They are more comfortable to wear and allow users to continue their daily activities.
Bionic prosthesis: easy to put on, intuitive to use
22/09/2020
Patients who receive a prosthesis after the amputation of a limb often have to train for weeks or months until they can control the technology and use it in everyday life without problems. At the Medical University of Vienna, the world's first bionic prosthesis has now been developed that has a closed control loop and enables immediate, intuitive use.
Big Data: early warning system for the ICU
03/08/2020
Patient monitoring systems in the ICU sound up to 700 alarms on average per patient per day, which boils down to one alarm every two minutes. An excessive number of them are false alarms. This generates vast amounts of data, which can make it difficult for doctors and nurses to identify the most critical alarms to manage. It also has a negative effect on the treatment of intensive care patients.
Stroke care: When every minute counts
02/06/2020
Stroke can affect anyone – older as well as younger people. The minutes after the stroke determine whether disability or death is the result. Only if acute care, inpatient treatment and rehabilitation are carried out in a targeted and effective manner, the chances are greater that only minor damage remains or that impairments even recede.
Comprehensive stroke care: faster, closer, better
02/06/2020
"Time is brain!" – a fundamental rule in stroke care because time is of the essence when brain regions are undersupplied with oxygen and glucose. If circulation is not restored quickly, brain damage can be permanent. However, the key point here is not just to "be fast", but also to "use the time to treat stroke effectively".

03/06/2019
They work with power, precision and tirelessly. This makes robots an ideal instrument for rehabilitation. In gait or motor training, movement sequences must be repeated thousands of times so that they can be learnt anew. What tires the patient and costs the therapist's time can easily be managed by robot-assisted systems. Learn more about the possibilities of robotics in rehabilitation.
Rehab with a robot – robot-assisted therapy in neurology
03/06/2019
It takes consistent repetitions if rehab patients want to relearn skills after surviving a stroke. This requires extreme effort. The industrial sector uses robots to perform repetitive tasks or handle jobs that require strength. What has been a fixture in factories for decades is now also making its way into rehabilitation facilities.
Cardiac arrhythmia: treatment in the linear accelerator
08/04/2019
Cardiac arrhythmia is a group of conditions where nerve cells trigger uncontrolled contractions of the heart muscle. They are treated with either medicine or catheter ablation of the tissue. In an interdisciplinary collaboration, cardiologists and radiotherapists took a different approach and used high-precision radiation therapy to treat a patient for whom the other options proved unfeasible.

01/04/2019
Our brain is the command center of our body. This is where all information and impressions are collected and converted into responses and movements. Modern imaging techniques offer physicians and researchers unique insights into the actions of the human central nervous system. The functional imaging technique allows them to watch our brain in action.
Brain mapping: preoperative planning with functional MRI
01/04/2019
A surgery already begins before the patient is lying on the operating table – namely with the planning. For example, if brain surgery is imminent, the brain must first be mapped. This makes the activity level of certain brain areas visible. Functional magnetic resonance imaging makes this possible.
SoftHand: grasping intelligence for lower arm prostheses
10/12/2018
So 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.
Brain stimulation: treatment using electric current and magnetic fields
03/12/2018
The 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.
