Cortico-subthalamic white matter tract strength predicts interindividual efficacy in stopping a motor response

► Created STN atlas probability maps based on ultra-high resolution 7T MRI images. ► Individually segmented STN masks and probability maps were used to test cortico-subthalamic white matter strength. ► Tract strength measures were taken to investigate the efficacy to withhold a motor response. ► Results show increased white matter tract strength between the pFMC and STN to account for better stopping behaviour.
