But move forward through time and fine tune the Pre-SMA research to see if it holds — A dissociation between stopping and switching actions following a lesion of the pre-supplementary motor area Intro Although the pre-supplementary motor area (pre-SMA) is one of the most frequently reported areas of activation in functional imaging studies, the role of this brain region in cognition is still a matter of intense debate. Here we present a patient with a focal lesion of caudal pre-SMA who displays a selective deficit in updating a response plan to switch actions, but shows no impairment when required to withhold a response – stopping. https://www.sciencedirect.com/science/article/pii/S0010945214002573
