From University Pompeu Fabra --> To University of Ulm From June 25 to July 6, I worked in the faculty of Engineering, Computer Science and Psychology at Ulm University, in Germany. I carried out my research activities in the Institute of Neural Information Processing under the supervision of Prof. Dr. Dr. Daniel Braun. We jointly worked in the characterisation of complex dynamical systems. The objective of the research mobility was to analyse the signals that I study in my PhD with techniques contributed by the host institution in Ulm. In particular, we applied complexity measures to EEG signals from epilepsy patients. The joint interdisciplinary approach that arise from the synergy of both groups can lead to a better insight into dynamics derived from complex physiological systems such as the brain.
