Beiträge von Kortex und Basalganglien zum Erlernen sequentiellen Verhaltens: Untersuchung mittels Neurostimulation, Modellierung, Magneto- und Elektroenzephalographie.
Zusammenfassung der Projektergebnisse
This project shed new light on our understanding of the processes and brain mechanisms mediating learning and monitoring of sensorimotor sequences, both in patients with movement disorders and in healthy human subjects. Using piano performance as experimental setup, we were able to investigate the neural mechanisms at the cortical and subcortical level engaged in (i) the encoding of sequence boundaries, (ii) the integration between auditory and motor information during sequence learning, (iii) the control of the timing of a skilled performance, (iv) how processing interoceptive cardiac signals influences error-monitoring. The results significantly expand the knowledge on the human action-monitoring system along two lines. Firstly, they provide new information about the cortical and subcortical processes associated with monitoring acquisition and execution of action sequences. Secondly, they also emphasise the need to consider interoceptive signals and brain-body interactions in these investigations. Furthermore, the data help elucidate the functional significance of basal ganglia and cortical oscillations.
