Besser vernetzt

HirnforscherInnen entschlüsseln Denkweise kreativer Menschen

Dem Überraschungsbesuch ein exquisites Abendessen servieren, den Fehler im Computerprogramm umgehen, ein Liebesgedicht verfassen: Einfallsreichtum ist in allen Lebenslagen hilfreich. Welche Netzwerke im Gehirn für solche spontane Handlungen nötig sind, hat ein internationales Forschungsteam nun herausgefunden, dem Psychologe Mathias Benedek von der Universität Graz angehört: Kreative Personen organisieren ihr Wissen flexibler und können dadurch entfernte Querverbindungen leichter herstellen.
„Was wir gelernt haben, speichern wir im sogenannten semantischen Gedächtnis. Das ist in der Regel gut strukturiert, was unter anderem hilfreich ist, um Bekanntes schnell erinnern zu können und um neue Dinge rasch zuzuordnen“, schildert Benedek. Bei kreativeren Personen ist das semantische Gedächtnis jedoch etwas weniger hierarchisch organisiert. Das fördert das flexible Denken.
Nicht nur die Querverbindungen im semantischen Gedächtnis spielen eine Rolle, auch die einzelnen Hirnareale, die bei kreativen Tätigkeiten aktiviert werden, sind anders miteinander vernetzt. „Diese Zusammenhänge zwischen dem Verhalten, den Gehirn- und den Gedächtnisnetzwerken konnten wir mit den Methoden der Komplexitätsforschung erstmals aufzeigen“, unterstreicht der Grazer Psychologe die Bedeutung der Erkenntnisse. Die Vernetzungen verändern sich ständig durch neue Erfahrungen. Somit lässt sich auch das kreative Denken prinzipiell steigern.

Die Ergebnisse der Studie, für die Mathias Benedek mit ForscherInnen des Pariser Brain Institute und des Israel Institute of Technology zusammenarbeitete, sind in der Zeitschrift „Science Advances“ erschienen.

Electrifying: Researchers film the first moments on the way from light to electricity

Physicists at the University of Graz (Austria), in collaboration with colleagues from Marburg University and Forschungszentrum Jülich (Germany), have achieved a scientific breakthrough. For the first time, the generation of electrical energy from light has been filmed and described theoretically. This work is of far-reaching significance, not least for optimising sustainable energy production from photovoltaics. This is because it provides fundamental building blocks for understanding the physical processes that take place, for example, in organic solar cells. The paper was published in the journal Physical Review X, one of the world’s most prestigious physics journals.

How can we teach using YouTube and AI? The University of Graz is strengthening media education in schools

A journey through the blood vessels using VR headsets brings biology lessons to life. An interactive quiz brings physics to life. The YouTube video explains the First World War. Whilst mobile phones are increasingly being banned from the classroom, social media platforms, apps and AI are playing an ever-greater role in knowledge transfer at school. But how can teaching with media be made even more effective? What are the challenges in media-based teaching? At the University of Graz, researchers are discussing these issues at a conference being held in Austria for the first time.

Jurassic Sounds: Biologist reconstructs insect songs from 165 million years ago

It was apparently not just the roars of the dinosaurs that made up the soundscape of the animal world during the Jurassic period. Crickets and grasshoppers communicated through a variety of songs and high-pitched sounds, as Thorin Jonsson from the Institute of Biology at the University of Graz discovered together with colleagues from the universities of Lincoln, Bristol (UK), Beijing (China) and Tempe (USA). The findings on what are so far the oldest traces of sound on Earth have just been published in the journal PNAS.
