News

    • With Yunzhe Liu at the Max Planck UCL Centre, we have a new preprint out on my first MEG investigation of sequenceness (replay) in humans (bioRxiv 2019). We find the memory decisions are based on rapid compressed replay of original experiences.
    • From my work with Christian Büchel, we published a paper on the role of the OFC in learning predictions of distant states in Nature Communications (2019).
    • From my work with Russ Poldrack funded by the DFG, we published a paper on the effects of temporal spacing on reward learning in the Journal of Neuroscience. In addition to multivariate fMRI results, we find that "spaced" training establishes longer-lasting value associations, while typical "massed" single-session learning is related to working memory capacity.
