title: Contralateral Cerebral Hypometabolism After Cerebellar Stroke: A Functional Near-Infrared Spectroscopy Study.
abstract: BACKGROUND
  We report the changes in cortical activity evaluated using functional near-infrared spectroscopy (fNIRS) in 2 cases with cerebellar stroke.
  
  
  METHODS
  Using an fNIRS imaging system, changes in the oxygenated hemoglobin concentration (ΔOxy-Hb) from baseline were estimated. Design and verbal fluency tasks were conducted for evaluation of visuospatial and language functions, respectively.
  
  
  RESULTS
  The contralateral prefrontal area showed limited activation compared with the ipsilateral one in the case with either cerebellar stroke.
  
  
  CONCLUSIONS
  A negative impact of cerebellar stroke on the multimodal association of cortex, regardless of the type of stroke (infarct or hemorrhage).
