Outcome Measures

Primary Outcome Measures

  1. Extent of neural activation in visual cortex measured by the number of voxels [1 day]

    compare the extent of neural activation in visual cortex between groups

Secondary Outcome Measures

  1. extent of neural activation in visual cortex measured by the number of voxels [1 day]

    compare the extent of neural activation in the different area visual cortex between groups
