Delighted to share our work on replay and successor representations! We find replay during very short task pauses in human visual cortex that is linked to learning SRs & happens when learning is implicit. Study led by

So proud of my partner’s performance at
#CCN25
in collaboration with aiar collective. EEG-modulated live set where different frequencies change the sound of the synthesizer. Speakers and light tubes are synced to the different EEG channels. I’m biased, but I think this is so cool!

New preprint! How do we integrate new information into prior knowledge? We find that existing knowledge enables rapid new learning but that interleaved replay during sleep promotes integration of new and old information. Modeling suggests a sleep context suppression mechanism.

Does sleeping on an idea work? Here’s what science says.
Scientists are finding experimental evidence that the transition between wakefulness and sleep is a portal for creative thought.

interested in abrupt shifts in behavioral strategy, and which factors can cause them in neural nets? anika elegantly boiled it down to the simplest case and shows that noise, gating and regularisation can make very simple neural nets „pop“. truly enjoyed this collab in a great team
