Zusammenfassung

Writing is a highly overlearned and complex movement. Functional MRI studies showed the involvement of both cortical and subcortical structures. A characterization of the dynamic interplay between the structures involved in writing is lacking up to now. We studied simultaneously brain activity with magnetoencephalography (MEG) and muscle activity with surface electromyography (EMG) during writing in 11 healthy subjects. Taking the muscle activity as reference we localized brain regions involved in the writing task by using the analysis tool Dynamic Imaging of Coherent Sources (DICS) and characterized the dynamic…
