“The brain is a complex biological organ of great computational capability that constructs our sensory experiences, regulates our thoughts and emotions, and controls our actions.”

Die Faszination für die neuronalen Grundlagen komplexer menschlicher Fähigkeiten bildet die Grundlage unserer Forschung.

Unsere Arbeitsgruppe erforscht die neuronalen Grundlagen motivationaler und kognitiver Kontrollprozesse im Kontext verschiedener mentaler Anforderungen. Dazu zählen:

  • Multitasking-Situationen, in denen mehrere Aufgaben (fast) gleichzeitig bearbeitet werden.
  • Arbeitsgedächtnisanforderungen, bei denen kurzzeitig Informationen im Gedächtnis behalten und bearbeitet werden müssen.
  • Anforderungen an das Prospektive Gedächtnis, in denen einmal gefasste Absichten zu einem späteren Zeitpunkt realisiert werden.
  • Zeitschätzaufgaben, in denen Zeitintervalle ohne externe Hilfsmittel eingeschätzt werden müssen.

 

Wie motivationale Prozesse und interindividuelle Unterschiede die Bearbeitung solcher Anforderungen modulieren, betrachten wir aus verschiedenen Perspektiven. Neben der Rolle von externen Belohnungen erforschen wir insbesondere auch, wie intrinsische Motivation wirkt und inwiefern motivationale und emotionale Prozesse Aufmerksamkeits- und kognitive Kontrollprozesse gemeinsam beeinflussen.

Dazu nutzen wir Verhaltensmaße sowie neurowissenschaftliche Methoden, wie funktionale Bildgebung (fMRT) und psychophysiologische Methoden (EEG). Aktuell setzen wir insbesondere auch multivariate Analyseverfahren ein, um die zugrundliegenden Aufgabenrepräsentationen zu charakterisieren und zu individuellen Unterschieden und Trainingseffekten in Bezug zu setzen.

Im Fokus steht für uns das Verständnis der Rolle präfrontaler Hirnstrukturen in ihrem Zusammenspiel mit anderen cortikalen und subcortikalen Regionen. Um die Rolle des Neurotransmitters Dopamin in diesem Zusammenhang zu erforschen, führen wir u. a. auch genetische Assoziationsstudien durch.

Viele unserer Studien führen wir mit jungen, gesunden Proband:innen durch, um das Grundverständnis der beteiligten neurokognitiven Prozesse zu erweitern. In verschiedenen Kooperationsprojekten betrachten wir diese Prozesse aber auch über die Lebensspanne mit Fokus auf Veränderungen und Trainierbarkeit im höheren Erwachsenenalter.

Self-determination: independent effects of choice and affective processing on the late positive potential (LPP), doi.org/10.1007/s11031-026-10251-4

Die im Rahmen der Promotionsarbeit von Sofia Kontaxi entstandene Arbeit beschäftigt sich mit dem Zusammenspiel von intrinsischer Motivation und Emotionsverarbeitung. In zwei EEG Experimenten konnte gezeigt werden, dass ein spezielles emotionsbezogenes ereigniskorrelierte Potenzial (LPP) auch motivationale Manipulationen (‚self-determined choice‘) reflektiert. Die motivationale Manipulation scheint jedoch die emotionale Verarbeitung nicht zu beeinflussen, sondern zeigt unabhängige Effekte auf das LPP. Die Ergebnisse werden in Bezug auf resourcenlimitierte Aufmerksamkeitsprozesse im Kontext motivational-affektiver Verarbeitung interpretiert. 

 

Neue Publikation in Human Brain Mapping erschienen: Network Neuroscience of Human Multitasking: Local Connections Matter
Die Befunde der fMRT-Studie zeigen, dass individuelle Unterschiede in modalitätsspezifischen Multitaskingkosten mit umschriebenen funktionellen Konnektivitätssunterschieden zusammenhängen, nicht aber mit Unterschieden in globalen Netzwerkkonfigurationen.

Wir gratulieren Dr. Marie Mückstein zur erfolgreichen Disputation und damit zum Abschluss einer exzellenten Dokotorarbeit. Für die folgende Postdoc-Zeit in Senne Braem's Arbeitsgruppe in Gent wünschen wir ihr alles Gute.
