Functional magnetic resonance imaging (fMRI)
Functional Magnetic Resonance Imaging (fMRI) is a neuroimaging technique that allows for non-invasive investigation of brain function. Functional MRI uses MR imaging to measure the tiny metabolic changes that take place in more active parts of the brain: Using radiofrequency pulses and a strong magnetic field, images of the brain can be acquired. Functional MRI has […] Read more...
Combining TMS & fMRI
Approaches Magnetic Resonance Imaging and Transcranial Magnetic Stimulation (TMS) have both immense potential in the field of neuroscience: fMRI before, after and during brain stimulation Magnetic resonance imaging complements brainstimulation in different ways Concurrent TMS/fMRI Methods for concurrent use of imaging and TMS were developed to examine evoked responses in detail. This combination allows for […] Read more...
Concurrent TMS/fMRI
We’ve developed and validated a concurrent TMS/fMRI setup to manipulate and measure brain activity at the same time. This online approach of combining Transcranial Magnetic Stimulation (TMS) with functional Magnetic Resonance Imaging (fMRI) allows for assessing TMS-induced brain activity on an individual level. A dedicated MR coil array allows for high-sensitivity fMRI, particularly at the […] Read more...
Transcranial Magnetic Stimulation (TMS)
Transcranial Magnetic Stimulation (TMS): Exploring and Treating the Brain Transcranial Magnetic Stimulation (TMS) is a tool that has significantly advanced our understanding of the brain and its functions. Introduced over 40 years ago, TMS allows researchers and clinicians to non-invasively stimulate specific brain regions using localized magnetic pulses. These magnetic fields pass the scalp, skull, […] Read more...

Retinotopic Mapping
One of the regions best examined by functional MRI (fMRI) is the occipital lobe, in particular the visual cortex, which is the main target for visual signals and the center of visual processing. Not all of the visual cortex is engaged with processing every visual signal. The regions of the primary visual cortex are responsible […] Read more...
Creativity research
What happens in your brain when you have an Aha -moment? While creativity is a construct that is hard to define and creative performance is even harder to measure, the common phenomenon “Aha Moment” is linked to many creative achievements. Signified as the process of linking old knowledge in an original way, it is thought […] Read more...
Resting State fMRI
What is Resting state connectivity? In classical task-based fMRI the neuronal activity is studied while performing a well-defined task, e.g., making a decision, commonly with the goal of localizing the brain regions responsible for the task that was carried out. Resting state fMRI (rsfMRI), on the other hand, is concerned with the neuronal activity in the […] Read more...
Dynamic causal modeling
Dynamic causal modeling (DCM) is a hypothesis-‐‑driven analysis approach based on Bayesian model comparison procedures (Bayes, 1763; Friston et al., 2003; Jeffkeys, 1939). DCM can be seen as an extension or generalization of fMRI analysis based on the general linear model. The application of DCM allows for creation of neural models to assess the dynamic […] Read more...
Manual Operation for 4th Generation Airliners – Man4Gen
What happens in a plane’s cockpit and pilot’s brain? In the EU project Man4Gen, we are cooperating with the National Aerospace Laboratory of the Netherlands, the German Aerospace Center, Airbus, Boeing, and the University of Vienna, amongst other partners. Main research topic of the Man4Gen project is to investigate safety issues in civil aviation and […] Read more...
