Klodiana-Daphne Tona

Klodiana-Daphne Tona studied psychology at the National and Kapodestrian University of Athens, Greece. As part of her training she did two clinical internships and functioned as peer consultant at the faculty of psychology.  After one  year of clinical practice at the Neurology Department of Aiginition hospital she moved to the Netherlands, where she  graduated in the Research Master’s programme in Cognitive Neuroscience at Radboud University, Nijmegen. There she studied the effects of noradrenalin on fear memories at the Donders Center for Brain and Cognition. She is currently working as a PhD candidate at the Cognitive Psychology section and the Leiden Institute for Brain and Cognition under the supervision of Professor Sander Nieuwenhuis. Her research focuses on the neuronal mechanisms of the  locus coeruleus- noradrenergic system in humans and the effects of the neuromodulator noradrenaline on cognition and emotions (functions and malfunctions).
