Guillén Fernández

from Wikipedia, the free encyclopedia

Guillén Santiago Eusebio Fernández (born August 12, 1964 in Bonn ) is a European neuroscientist and neurologist .

Life

Fernández studied medicine at the Rheinische Friedrich-Wilhelms-Universität in Bonn . In 1994 he received his license to practice medicine . A year later he received his doctorate before habilitation in 2001 with Christian E. Elger . After clinical training as a neurologist and scientific work at the University Hospital Bonn (Elger, Wolfgang Maier ) and Magdeburg ( Hans-Jochen Heinze ) as well as at Stanford University ( John Gabrieli ), he became a research group leader at the Donders Institute for Brain, Cognition and Behavior at the Medical Center in 2002 Faculty ( Radboud Universitair Medisch Centrum ) of Radboud University in Nijmegen (Netherlands).

Four years later, Fernández was appointed Professor of Cognitive Neuroscience and, in 2010, Director of the Donders Institute. Fernández was elected a member of the Memory Disorder Research Society (MDRS) in 2007 and was admitted to the Academia Europaea in 2014. In 2010 he was admitted to the European Research Council (ERC) as an Advanced Investigator . In 2018 Fernández was elected to the Royal Dutch Academy of Sciences .

Fernández researches the neural basis of memory processes. He combines cognitive paradigms with functional magnetic resonance imaging (fMRI), various EEG techniques and occasionally pharmacological interventions or genetic analyzes. He dealt primarily with memory formation and stabilization and examined in particular how existing knowledge or emotions influence these processes.

Together with colleagues, he showed how, within the first two seconds, two different neural processes in the medial temporal lobe system contribute to the fact that read words can be remembered later. In studies of the subsequent stabilization of memory during sleep, he was able to show how the contribution of the medial temporal lobe system is taken over by a specific region in the prefrontal cortex . This region is particularly involved in integrating new knowledge with existing knowledge. These mechanisms are important for knowledge acquisition and have therefore found their way into educational research.

In studying the interaction between memory and emotion, Fernández et al. Discovered a shift in network activity that affects almost the entire brain that occurs when individuals feel threatened. This shift is caused by the neurotransmitter noradrenaline and limited or terminated by the stress hormone cortisone . It leads to far-reaching changes in cognitive processes including memory, danger perception and working memory. The activity balance of these networks is genetic and determined by previous experiences of significant dangers. These discoveries have led to a mechanistic model of hazard response that has received widespread attention in biological psychiatric research.

Awards

Fernández received the Richard Jung Prize of the German Society for Clinical Neurophysiology (DGKN) in 2002 and the Vici Prize of the Dutch Research Foundation (NWO) in 2005 . In 2016 he received the International Hermesdorf Award .
