This is the website of Marius Zimmermann, postdoctoral researcher at the Institute of Psychology at the University of Regensburg. I am interested in the way we plan and coordinate actions, when acting alone (action planning), when performing actions together with other people (joint action), and when perceiving actions of others (action observation). I use behavioural and neuroimaging methods (MRI, TMS, EEG) in healthy subjects to study how neural structures and functions support action related cognition.

Delighted to share our new paper Intra-individual behavioural and neural signatures of audience effects and interactions in a mirror-game paradigm in Royal Society Open Science (@RSocPublishing) with @SineLabDTU and @schiano_arianna. In this study we investigated the behavioural (kinematics) and neural (EEG) mechanisms of observed actions and interactions.

Intra-individual behavioural and neural signatures of audience effects and interactions in a mirror-game paradigm
We investigate behavioural and neural mechanisms underlying observed actions and interactions in comparison to individual actions.
Larger movements were produced when being observed; and observed actors and interacting dyads produce slower and more predictable movements in contrast to acting alone. EEG results show increased mu suppression during interaction, and to a lesser extent during observed actions.
Functional brain connectivity increased during observed actions relative to both individual and interactive actions, suggesting increased intra-individual monitoring and action-perception integration as a result of audience effects.
23-06-2021 Talk at ESCAN2021
One year late, ESCAN 2021 will take "in" Budapest, where I will give a talk on our interbrain synchronization adventures in the session The neural mechanisms underpinning joint action.
01-06-2021 Job update
As of June 1, 2021, I will be working in the research group of Prof. Angelika Lingnau at the Chair of Cognitive Neuroscience, University of Regensburg. The work will center around neural representations of actions during planning and observation. Looking forward to new challenges - and hilly routes on my commmute to work!
10-12-2020 Talk in Aalto, Finland
Getting lots of feedback and discussion on effects of SNR on inter-brain connectivity at a talk at the Neuroimaging methods group (NIMEG) at Aalto University.
08-08-2020 Talks in Regensburg and Munich
Before the summer break I have been presenting our current work at the Cognitive Neuroscience Research Colloquium at Regensburg University, as well as at the CVBE e-Lab meeting at the Ludwig-Maximilians University Munich. Thanks to both groups for the invitations!
11-07-2020 FENS2020 Virtual Forum
This summer I have been presenting our work on inter-brain mechanisms of social interaction at FENS 2020 Virtual Forum. You still have the chance to check out our poster.
22-06-2019 Poster accepted for EuroCogSci 2019
I am going to present a poster on our dual-EEG work on joint action at the European Conference for Cognitive Science 2019 (EuroCogSci) in September in Bochum (Germany). But first heading to the Joint Action Meeting (JAM8) taking place in Genova (Italy) during the second week of July, where SINe Lab head and members Ivana Konvalinka and Arianna Schiano will be giving talks on interpersonal coordination and joint attention, respectively.
18-06-2019 Manuscript accepted in Journal of Cognitive Neuroscience
A manuscript on processing of multiple overlapping task timelines in the context of multitasking has been accepted in the Journal of Cognitive Neuroscience. Based on an fMRI study conducted at Stockholm University we suggest that multiple overlapping task timelines/deadlines are represented spatially, possibly through embodied cognition.
01-01-2019 New postdoc position at SINe Lab at DTU Copenhagen
In January 2019 I started a new postdoc position, moving from Stockholm, Sweden to Copenhagen, Denmark. I will be working in the Social Internation and Neuroscience group (SINe Lab) at the Technical University of Denmark (DTU) with Ivana Konvalinka. The project investigates neurophysiological mechanisms underlying interpersonal coordination in joint action using real-time dual-EEG. More about the project can soon be found here.
16-07-2017 Paper accepted in Brain Structure and Function
A new paper has been accepted in Brain Structure and Function. In the paper Is the extrastriate body area part of the dorsal visuomotor stream? we report that functional and structural connectivity profiles indicate that EBA interacts more strongly with dorsal-stream regions compared to other portions of the occipito-temporal cortex involved in processing body parts (FBA) and object identification (LOC). These findings provide anatomical ground for a revision of the functional role of EBA.
28-12-2016 Starting as postdoc
Starting January 2017 I will be working as postdoctoral researcher at the Psychology Department at Stockholm University. Together with Prof. Timo Mäntylä I will investigate how to coordinate multiple action plans and action goals in multitasking settings.
23-11-2016 PhD thesis defended
On November 23, 2016, I successfully defended my PhD thesis entitled “A cortical mechanism for translating action goals into action plans”, at the Radboud University Nijmegen, the Netherlands.
Many thanks to my supervisors, members of the manuscript committee and corona, and my colleagues, friends and family that supported me during my PhD and joined me in the celebrations.
A digital copy of my thesis can be downloaded here. If you prefer a printed copy feel free to contact me.
