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).


Joint Action (2019 - ongoing)

Neurophysiological mechanisms underlying interpersonal coordination in joint action
In this project we are investigating the functional role of inter-brain synchronization on interpersonal coordination during joint action. Inter-brain synchronization is measured using dual-EEG (EEG hyperscanning).


Translating Action Goals into Action Plans (2010 - 2018)

Role of EBA during action planning
The extrastriate body area (EBA) has been defined as visual area involved in body perception. A number of studies showed that EBA is co-activated in motor control, however, the role of EBA in motor control remained unclear. In a series of studies using fMRI and TMS we showed that EBA represents desired goal states that can later be used by dorsal stream areas for the generation and execution of action plans.

Internal simulations during action planning and action observation are body posture dependent
Using manipulations of body posture during action planning and action observation tasks we could show that both, planning and observing actions, rely on the same predictive mechanisms. The predictions implemented by this mechanism are based on the current physical configuration of the actors/obsevers body. Moreover, we could show that these predictions pertain to the goal state of the planned/oberved action.

Connectivity profile of Extrastriate Body Area
A brain region's function depends on its connections with other parts of the brain. We provide anatomical evidence, using resting-state fMRI and diffusion MRI, that EBA may indeed be involved in motor control tasks. Specifically, we could show that EBA has stronger connections with the dorsal visual stream involved in action planning, compared to other visually defined areas located in the ventral visual stream.
