P28. The functional role of the anterior intraparietal sulcus for recovery of hand function in chronic stroke patients – A combined fMRI-TMS study

After stroke, neuroimaging studies frequently show increased activation of contralesional regions such as the primary motor cortex (M1) and the anterior intraparietal sulcus (aIPS) during movements of the impaired hand (Rehme et al., 2012). There is evidence that these areas may adopt either supportive or disturbing implications for motor control, depending on multiple factors, such as age, stroke severity, and lesion location (Di Pino et al., 2014). Importantly, previous research has mainly focused on investigating this question in the contralesional M1, while other areas involved in motor control, such as the aIPS have often been neglected despite considerable changes in post-stroke activity.
