Bimanual Coordination
We study how different control processes contribute to stabilizing the coordination between limbs, and how they change as a function of, e.g., movement frequency and amplitude, learning, development and pathology.Relative Phase Dynamics
The stability of coordination can often be addressed via the relative phase between the individual limb movements. We are studying in detail the effect of different interactions between limbs, effects of noise and non-autonomous forcing.
