Before the exchange
Learning Agreement
Before you go abroad, you should fill out a Learning Agreement. The Learning Agreement lists the courses that you will attend at the host university and how these courses will be recognized at TU Dortmund University.
Please arrange an appointment with the contact for internationalization as soon as you have selected your courses at the host university to discuss the recognition in Dortmund.



![3D visualisation of human neuronal tissue reconstructed by multi-scale X-ray phase contrast tomography. Neuronal cell nuclei are shown in yellow for the granule neurons in the dentate gyrus region of the hippocampus. Blood vessels are shown in red. By changing the X-ray optical magnification in the multi-scale recordings, one can zoom into regions-of-interest (red ovals). In these scans the resolution is high enough to resolve sub-structures of the nucleus, associated with different DNA packing regimes.
