How does the brain work? A little bit on neurons, synaptic plasticity, and why sleep is important – and dreams can be straaaange…
In amygdala we trust
I wrote an article for the nature portfolio blog about our new amygdala paper. You can read how breaking apart the almond-shaped amygdala into its subnuclei helped us to find out more about how people learn to distinguish between trust makers and trust breakers.

@orf1 – Fanny’s Friday Doku
Susanne Kainberger and the Fanny’s Friday team invited me to do a feature show on fear and anxiety together with the psychotherapist Renée Fellmann-Pozdena, the neuroscientists Daniela Pollak-Monje Quiroga (MedUni Wien) and Wulf Haubensak (IMP Wien), as well as Manuel Rubey (actor, comedian) and Bernhard Egger (musician, youtube host).
If you missed it, there was also a front page news article on orf.at.
Vienna Cognitive Science Hub: Predictive Processing Symposium
The Vienna Cognitive Science Hub invited me to do an intro lecture on Predictive Processing, moderate the Q&A session with Karl Friston and to host their panel discussion with Karl Friston (University College London),
Naoshige Uchida (Harvard University), Isabella Sarto-Jackson (Konrad Lorenz Institute for Evolution and Cognition Research), Moritz Grosse-Wentrup (University of Vienna), and Manuel Zimmer (University of Vienna).
Predictive Processing and the Free Energy Principle?! Count me in!
Please find all the exciting talks on the symposium’s website.
@orf1 – Fanny’s Friday
Another one on fear, this time acrophobia. Normally I assume that everything on TV is staged for your entertainment. The wonderful Isabella Purkart who interviewed me was really, really terrified of heights. The whole show was quite an ordeal for her. At the end, she managed to climb all the 183 of the Vienna Jubiläumswarte. Not only was she rewarded with a fantastic view over our city and the Wienerwald, she also got a first hand experience how confrontation helped her to overcome her fear. Great job!
Why are we excited about predictive processing?
The lovely people from the brainstorms group invited me to give an online talk about predictive processing. Predictive processing theory suggests that all brain functions depend on comparisons between ongoing actual experiences and the brain’s expectations. It suggests that expectations and predictions about reality are, probably, more important than the direct live sensory evidence that the brain receives. But is it just a new data modelling method? Does it describe just one aspect of cognition? No, there is much more potential. Let us look at the loose ends of present day cognitive (neuro)science to see why we can be really excited about predictive processing.
@orf2 – Covid-19, whatever next?
Using our brain we predict the future based on what we have learnt in the past. But what if there is no precedence to learn from? How can we cope with lock-downs, isolation, existential crises, and fear of an unknown infection?
Covid-19 brings most of us out of their comfort zone but we are built for enduring hardships and uncertainty.
I was invited to an afternoon TV talk show to discuss my outlook on the future with social economics Prof. Marina Fischer-Kowalski, psychologist Irina Nalis, behavioral biologist Gregor Fauma and Matthias & Tristan Horx.
The Interdisciplinary College (IK) will take from 13 to 20 March 2020 in Günne/Möhnesee, Germany, with this year’s focus theme: Curiosity, Risk & Reward: Shaping Autonomous Intelligence.
Together with Till Bockemühl (University of Cologne) I will teach Introduction to Neuroscience
The brain, the cause of – and solution to – all of life’s problems. According to our brains it is the most fascinating structure in the known universe. Consisting of about 86 billion neurons of which each can form thousands of connections to other neurons it is also the most complex structure in the known universe. In this course we would like to give you a rough guide and introduction to the basic principles, fundamental theories, and methods of neuroscience.
We will demonstrate that neuroscience can be seen as a multi-modal, multi-level, multi-disciplinary research framework that aims at addressing the challenges of this megalomaniac scientific endeavor. We will see that different frameworks and methods can lead to conflicting empirical evidence, theoretical assumptions, and heated debates. However, we argue that this might be the only way to uncover the mysteries of our brain. Read more about our course.
@orf1 – okidoki on fear
Finally, I was asked for an interview in the children’s television show okidoki. A childhood’s dream come true :) I was asked to explain what happens in the brain and the body when we are afraid. A very suitable topic for Halloween, I guess.
More evidence for dopamine’s involvement in creativity
Anna-Lisa Schuler has been working on our CREAM data and found out that people with stronger brain connectivity of the dopaminergic midbrain also show higher levels of creativity. She did her analysis on resting state data, this means, at that time our participants did not perform any specific task. Instead, while lying inside our comfortable MRI scanner, they engaged in daydreaming. Karl Friston has called this state of mind unconstrained cognition because people are not distracted by our experimental stimuli.
We previously observed stronger dopaminergic midbrain connectivity in people who have an Aha! moment. Now, Anna-Lisa’s new finding links a personality trait to brain connectivity. The next question is, does frequent engagement in creative trinking and repeated experience of Aha! moments boost your creativity – or are creative people more likely to have Aha! moments?
