Congratulations Lukas

On Thursday, 28th April, Lukas Hahn defended his PhD successfully.

We are very proud of Lukas and his outstanding work! His excellent dissertation entitled “Proximate and ultimate causes of working memory capacity: Comparative electrophysiological studies in birds” was graded with summa cum laude.

Congratulations Lukas!


Today, we proudly congratulate Will Clark for his THINK@Ruhr Postdoctoral fellowship! In the next three years, Will is going to compare the neural coding principles of the avian visual layers with the primates, rodents, and computational models of object recognition.

New paper published

Dorian Röders, Anne Klepp, Alfons Schnitzler, Katja Biermann-Ruben and Valentina Niccolai investigated semantic processing of onomatopoetic verbs (e.g., “tröpfeln”—to dripple) using MEG. Their findings suggest increased cortical activation related to onomatopoeias in linguistically relevant areas and extend our knowledge on cognitive simulation processes.

New preprint available on bioRxiv:

Lukas HahnDmitry BalakhonovMikael LundqvistAndreas Nieder and Jonas Rose: Oscillations without cortex: Working memory modulates brainwaves in the endbrain of crows.

Cognitively modulated local field potentials in the avian brain appear very similar to those found in mammals. This indicates that neural networks required for higher cognition have evolved in parallel.

New eLife paper published

In their study, Lukas Hahn, Dmitry Balakhonov, Erica Fongaro, Andreas Nieder and Jonas Rose show that the neural mechanisms that limit working memory capacity in primates also limit working memory capacity in crows. By enabling such cross-species comparisons, they foster our understanding on cognitive computational constrains.
