MRI methods
We investigate various methodological aspects of MRI data aquisition
Changes in brain structure due to external influences
Does it make a difference if you show a video to the subject while acquiring a structural scan? Yes, it does! We have recently found that visual stimuli during the acquisition of anatomical images lead to measurable changes in the thickness of the cerebral cortex. This finding is important for clinical studies investigating disease-related changes in brain structure. In addition, visual stimuli during the examination can distort the so-called "laminar fMRI" studies (measurement of brain signals from different layers of the cerebral cortex). We are interested in further research into the causes of this effect.
Advantages of high-field MRI
Images from high-field MRI are not only more beautiful. Higher spatial resolution, made possible by the higher magnetic field, also allows us to examine the function of small intracortical structures such as columns and layers, as well as subcortical structures.
