Manfred-Stärk-Symposium 2022 - Sep. 11-12

Special symposium on theoretical neuroscience and neuromorphic computation dedicated to our generous benefactor Manfred Stärk and his foundation.

Nacht der Forschung 2022 - Info
We were delighted to be among the 750 researchers from the University of Bern who presented their research to tens of thousands of people.

Visitors to our stand got an insight into learning in neural networks and neuromorphic engineering by experiencing the dynamics of real biological neurons using our in-house electronic neuron circuit. The public could also compete against an AI by playing the puzzle game Tic Tac Toe, also known as Noughts and Crosses.

CNS*2022 - Computational Neuroscience Meeting - July 16-20 - Info

"Latent Equilibrium: A unified learning theory for arbitrarily fast computation with arbitrarily slow neurons" and
"Bio-inspired AI and AI-inspired biology."

Sinergia Meeting at the Gurten (July 5)
The last meeting of the consortium funded by the SNSF Sinergia grant on
"Neural Processing of Distinct Prediction Errors."

We enjoyed working with the groups of Fritjof Helmchen, Giacomo Indiveri, and Simon Sprecher in such a fruitful collaboration!
