Outcome Measures
Primary Outcome Measures
- 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
- 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
