Structural connectivity in pre- and primary motor cortex
Age-related changes in pre- and primary motor cortex
Age effects in bimanual coordination
The world-famous pianist Vladimir Horowitz completed his final recording four days before his death. The recording consisted of a repertoire Horowitz had never previously recorded. He died in 1989 at the age of 86. In terms of well-tempered bimanual coordination, Horowitz was certainly more an exception than the rule. In fact, for most of us playing the piano forms a major hurdle, irrespective of age, as moving our hands and fingers accurately and independently is not easy. Most probably this difficulty stems from a cross-talk of activity from one side of the body to the other. It is the mere symmetry of the central nervous system that renders the inter-hemispheric cross-talk prominent, probably more so when movement-related neural activity becomes synchronized.
Launch Date: 2013
Duration: 5 Years
Funding: EU Erasmus Mundus / Charité
- We study the relationship between altered inter- and intra-hemispheric structural and functional connectivity in the bilateral motor network. Our focus is on the correlation between connectivity and declined motor performance in older adults.
- Behavioral paradigms contain (the learning of) bimanual coordination.
- Functional connectivity is assessed through EEG and fMRI.
- Structural connectivity is determined via DWI-based tractography.

Related Research Themes & Projects
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.
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.
