Vortrag von Dr. Katja Kornysheva

A common view in motor skill acquisition is that learning transforms actions from associative to motor reference frames, culminating in holistic movement representations that function like pre-programmed trajectories. In this talk, I will outline an alternative perspective, based on MEG, fMRI and behavioural findings. I will argue that, in humans, even highly practiced, seemingly automatic skills are not retrieved holistically from stored motor programs. Rather, they are dynamically assembled from smaller functional components, and draw on areas traditionally linked to declarative memory contributing to action planning. This hierarchical and flexible control architecture enables skilled actions to adapt to changing task demands with relevance to the rehabilitation of movement disorders.
