Representative map of brain activation during the visual stimulation paradigm (the standard BOLD measurement) for the SCA (upper row) and brain tumor control (lower row) patients, who had the median activation volume in the corresponding group. The activation volume was significantly smaller in the SCA patient than the control patient (activation thresholds: p = 0.001 and k =5).
