In the search for neuroanatomical correlates of this multifaceted disturbance, this study employs two distinct, well-defined tasks of close association to motor inhibition and decision-making impulsivity, Go/No Go and Delay discounting. Although conceptualized as a result of non-physiologic chronic dopaminergic stimulation, recent advances speculate on combined disruption of other networks as well. The phenomenon of impulsivity in Parkinson's disease appears as an arduous side effect of dopaminergic therapy with potentially detrimental consequences for the life of the patients. 4Department of Neurology, School of Medicine, University of Minnesota, Minneapolis, MN, United States.3Department of Psychiatry, Faculty of Medicine, Masaryk University and University Hospital Brno, Brno, Czechia.2Center for Magnetic Resonance Research (CMRR), University of Minnesota, Minneapolis, MN, United States.1First Department of Neurology, Faculty of Medicine, Masaryk University and University Hospital of St.Pavel Filip 1,2 *, Pavla Linhartová 3, Pavlína Hlavatá 3, Rastislav Šumec 1, Marek Baláž 1, Martin Bareš 1,4 and Tomáš Kašpárek 3
