P109. Parietofrontal motor pathways and their association with motor function after stroke

A stroke results in widespread alterations of motor-related brain activity and interregional interactions in the sensorimotor network. Numerous studies have investigated the functional relevance of the primary motor cortices (M1) and predominantly frontal and prefrontal secondary motor areas. Only few studies focused on the functional role of the ventral premotor cortex (PMv) and the posterior parietal cortex (PPC) after stroke. Corticocortical interactions between M1, PMv and posterior parietal motor areas, such as the anterior (aIPS) and caudal intraparietal sulcus (cIPS) are relevant for skilled voluntary hand function.
