Lüder Deecke

Lüder Deecke (ˈdeːkə; born 22 June 1938) in Lohe-Rickelshof, Germany is a German Austrian neurologist, neuroscientist, teacher and physician whose scientific discoveries have influenced brain research and the treatment and rehabilitation of neurological disorders. Full professor and head, Department of Clinical Neurology at the University of Vienna Medical University of Vienna, professor emeritus since October 2006, Deecke is also head of the Ludwig Boltzmann Institute for Functional Brain Topography and is the author of a number of books and more than 600 publications in the fields of neurology, clinical neurology, neurophysiology, clinical neurophysiology, neurosciences, brain research, movement disorders, etc. His early research with Hans Helmut Kornhuber in the mid-1960s led to the discovery of the Bereitschaftspotential (or readiness potential), which is a measure of neural activity in the brain that precedes voluntary movements. This discovery set an important standard in research and rehabilitation of motor systems, and re-introduced the word will in key word registers. In 1964 Deecke performed as doctoral student of Hans Helmut Kornhuber, EEG-recordings in man accompanying volitional movements and actions, and they discovered a slowly increasing activation (negative deflection) in the EEG, which they called Bereitschaftspotential The term Bereitschaftspotential (BP) can be found in the ‘List of German expressions in English‘. In order to record brain activity prior to an unforeseeable event – which a voluntary movement undoubtedly is – it needs a special method: the reverse averaging, which was invented by Kornhuber and Deecke in the same year (1964). The full paper appeared in 1965 and was awarded a Citation Classic. In 1970 and 1971 Deecke was a research fellow in Toronto, Canada, under John M. Fredrickson. He performed experiments in the vestibular system (sense of balance) with rhesus monkeys and found the thalamic relay nucleus, nucleus ventralis posterior inferior (VPI) for the vestibular projection to the cortex.
