Professor Mai studied medicine in Freiburg, Germany, Vienna and UT Southwestern Medical School, Dallas, U.S.A. Student and Medical practices in Freiburg (Clinic for Neurosurgery), Berlin and Düsseldorf. Dissertation ("summa cum laude") and habilitation were awarded by the University of Düsseldorf: After a period as GP in private practice (Titisee-Neustadt) he became scientific assistant and senior assistant at the C. and O. Vogt-Institute for Brain Research, University of Düsseldorf (1972 - 1983) and Professor of Neuroanatomy at the Institute of Neuroanatomy, H.-Heine-University of Düsseldorf. He served as director of the Department of the Institute of Anatomy 1 until retirement in 2011. His main research interests are (i) the structural and molecular anatomy of the mammalian brain and (ii) expression patterns and regulation of terminal carbohydrates in development, cell activation and disease (III) operation planning in stereotactic neurosurgery. He works on a "Digital Brain Atlas for Planning and Interindividual Registration of Targets in Deep Brain Stimulation" and on a "Spatial Information Management Resource for the Human Brain". J. K. Mai has edited the catalogue of human brain sections from the Vogt collection; he is author and editor of several books, e.g. the awarded "Atlas of the Human Brain" (Academic Press/Elsevier, San Diego), "The Human Nervous System" (Academic Press/Elsevier, San Diego, Amsterdam, 3rd ed. 2012), Human Brain in Standard MNI Space: A Comprehensive Pocket Atlas (Academic Press/Elsevier, San Diego, 2017; with M. Majtanik), Funktionelle Anatomie für Zahnmediziner (Quintessenz, Berlin, 2nd. ed. 2008; Sensi Divini (ital., engl., ger, russ. eds). J. K. Mai is founder and CEO of MR-X-Brain GmbH.Milan Majtanik received his diploma in neuropsychology and training in neuroinformatics from the University of Bochum. He completed his diploma in mathematics and his PhD in psychology at the University of Düsseldorf. In his research at the Research Center Jülich he combined advanced analysis techniques in magnetoencephalography (synchronization tomography) with computational modelling in order to measure the impact of desynchronizing sensory stimulation on brain functions. His work on neural plasticity and desynchronizing neural stimulation provided framework for the developent of novel therapeutic techniques. He is currently focusing on the development of novel algorithms for high precision mapping and analysis of individual MRI scans.
