Rainer Goebel - Short BiographyAfter his study of psychology and computer science in Marburg, Germany, (1983-1988), Rainer Goebel has worked on artificial neural networks of visual processing. He did his PhD at the Technical University of Braunschweig, Germany, (1990-1994) under Prof. Dr. Dirk Vorberg developing a large-scale oscillatory neural network model of scene segmentation, selective attention, and shape recognition. In 1993 he received the Heinz Maier Leibnitz Advancement award in cognitive science sponsored by the German minister of science and education for a publication on the binding problem and in 1994 he received the Heinz Billing award from the Max Planck society for developing a software package for the creation and simulation of neural network models. From 1995-1999 he was a postdoctoral fellow at the Max Planck Institute for Brain Research in Frankfurt/Main in the Department of Neurophysiology under Prof. Dr. Wolf Singer where he founded the functional neuroimaging group. In 1997/1998 he was a fellow at the Berlin Institute for Advanced Studies (“Wissenschaftskolleg zu Berlin”). Since January 2000, he is a full professor for Cognitive Neuroscience in the faculty of psychology and neuroscience at Maastricht University. Since 2005, he is director of the Maastricht Brain Imaging Centre (M-BIC). He served as chair for the Organization for Human Brain Mapping (Chair-elect 2006/2007, Chair 2007/2008, Past-Chair 2008/2009). Since 2008 he is team leader of the “Neuromodeling and Neuroimaging” group at the Netherlands Institute for Neuroscience (NIN). In 2014 he has been selected as member of the Royal Netherlands Academy of Arts and Sciences.
Research InterestsRainer Goebel’s core research interest is the question which neuronal representations are used in the brain and how they are processed to enable specific perceptual and cognitive functions. These questions are investigated by integrating neuroimaging with neural network modeling and the development of advanced analysis tools. Progress in understanding brain mechanisms are tested by neuroscientific applications including brain computer interfaces (BCIs) and neurofeedback studies. The following three sections describe the research topics currently studied most intensively.
Cracking the columnar-level functional code of the brainWith standard functional brain imaging (i.e. fMRI at 3 Tesla), we can routinely see specialised brain areas in the human brain, including “experts” for colour, visual motion, faces, words, language, planning, memory and emotions. This level of resolution reveals an amazing organisation of the brain that is similar, but not identical, across individuals. We still, however, know little about the representations coded inside specialised brain areas and how complex features emerge from combinations of simpler features when we move from one area to the next. With high-field MRI scanners (7 Tesla and beyond), the achievable functional resolution reaches to the sub-millimetre level (500–1000 microns). This is important since neurons with similar response properties seem to spatially cluster into functional units or cortical columns with a lateral extent of hundreds of microns. Studying the brain at the cortical columnar level seems to be the right level to reveal the principles that the brain uses to code information. I believe that this columnar-level code can indeed be "cracked" by adequately combining clever experimental designs (psychology), sub-millimetre fMRI (neuroimaging), sophisticated data analysis tools (signal analysis) and large-scale neuronal network modelling (computational neuroscience). Goebel believes that a massive attempt to crack the columnar-level code in as many areas as possible will ultimately lead to a deeper understanding how mind emerges from simpler units in the brain.
Neurofeedback and brain computer interfacesIn collaboration with Niels Birbaumer and Nikolaus Weiskopf, Goebel co-pioneered fMRI-based moment-to-moment neurofeedback with the development of the "Turbo-BrainVoyager" software package. After advancing real-time fMRI methods further, Goebel currently contributes to applications of fMRI neurofeedback as a novel therapeutic tool, e.g. for patients with Parkinson’s disease and depression (see TEDx talk above). Using fMRI and functional near infrared spectroscopy (fNIRS), Goebel, Sorger and colleagues use real-time fMRI also to develop communication BCIs for patients with severe motor impairments. Goebel also introduced the first interactive fMRI hyper scanning experiment where measured brain activity was used online to play “Brain Pong”. He currently extents real-time fMRI to the columnar level to enable content-specific neurofeedback studies and better communication BCIs.
Large-scale neuronal network modelingGoebel invented the “Common Brain Space” (CBS) modeling approach allowing for the first time to simulate and predict individual topographic neuroimaging data at different levels of organization reaching from networks to areas to columnar features; the CBS approach has been applied to explain visual illusions, selective visual attention and invariant object recognition and it will be used to model columnar-level feature representations measured with ultra-high field fMRI (see section above).
Besides these major topics, Rainer Goebel’s research activities also include:
- Artificial large-scale columnar-level neural network models of visual processing
- Neural correlates of visual attention, mental imagery and awareness
- Columnar-level cortical representations of auditory, somatosensory and multi sensory information
- Advanced methods for cortex-based statistics and brain normalization
- Portable brain-computer interfaces (BCIs) based on functional near infrared spectroscopy (fNIRS)
- Development of new analysis methods for structural and functional magnetic resonance imaging (fMRI) data
- Integration of spatially (fMRI) and temporally resolved (EEG/MEG) imaging methods
- Data-driven brain imaging analysis tools (Independent Component Analysis, ICA; Granger Causality Mapping, GCM)
- Investigating effects of temporary, virtual, lesions using Transcranial Magnetic Stimulation (TMS)
- MRI-based investigation of anatomical, functional and effective connectivity
Scientific Software DevelopmentRainer Goebel is a passionate programmer doing most of the coding for BrainVoyager and related software himself (see his BV Blog). Besides writing scientific papers and working with a group of intelligent young scientists, he views solving intricate problems through programming as the most challenging and rewarding activity in his scientific life. He is convinced that one of the most important activities of human beings is the creation of tools. The tools he enjoys creating are computer programs, such as BrainVoyager, which help many people to do better scientific and clinical research. His view on cross-platform development can be found in a press release by Nokia). He also enjoys developing free teaching software to help students learn about the human brain. His "BrainVoyager Brain Tutor" program won the runner-up prize for programming the "Best Original Commercial Qt Application" and his app Brain Tutor HD is available for iPad, iPhone and iPod Touch.
Rainer Goebel is also proud that an image created with BrainVoyager had been selected for inclusion in the famous OpenGL “red book” (see image on the right). This book is the definitive guide for learning 3D OpenGL programming. After learning OpenGL with the second edition of this book, it is a pleasure for him to see the fruits of his OpenGL coding efforts appearing in subsequent editions.
