Our research focuses on the development and optimisation of sequences and protocols for brain and spinal cord magnetic resonance imaging regarding modalities such as:

  • functional magnetic resonance imaging (fMRI)
    • real-time functional magnetic resonance imaging (rt-fMRI)
    • resting-state functional magnetic resonance imaging (rs-fMRI)
  • diffusion-weighted and diffusion tensor imaging (DTI)
  • network analysis
    • graph theory analysis of functionale brain networks

These techniques are applied to areas of research in fear conditioning, pain, object recognition, learning and memory.
