My research focuses on the connectivity of the human brain. To enable such complex cognitive functions as action planning and control, decision making, language processing or social interactions, different regions of the cerebral cortex, particularly of association cortices such as the parietal lobe, interact with each other and with subcortical structures. This is enabled via dense fiber connections between these regions, from large long-range fiber bundles to the single axons. Decoding this connectional architecture provides the structural prerequisite for understanding the functional interactions.
