A major line of our research is a more specific understanding of the measured MR signal during brain activation, the variability of this contrast across different cortical and subcortical regions, its dependence on the underlying structure and shape of the microvasculature, and the correlation of this contrast to neuronal activation as a function of spatial and temporal resolution.

Brain activation is (sometimes) reflected in changes of the acquired MR signal, and depending on the selected acquisition method, the signal may reflect underlying neuronal activation, or just very unspecific changes in local blood oxygenation or flow. [more]
MRI at extremely high fields requires a major effort in technical developments. A significant part of our research is thus devoted to capture as much as possible of the tiny magnetic waves emitted from the excited brain. [more]
Since its invention more than 20 years ago, functional Magnetic Resonance Imaging (fMRI) has played a central role in cognitive neuroscience. The aim of our research is to develop new mathematical methods for the analysis of both standard fMRI data (3 Tesla) as well as ultrahigh field fMRI data (≥ 7 Tesla). [more]
