Vascular effects on the BOLD response and the retinotopic mapping of hV4
Fig 8
Deterioration of hV4 was present in the left hemisphere of Subject 2 post correction, where a large amount of ipsilateral coverage appeared in the pRF density plot and the polar angle map is considerably disturbed (17.4% less smooth after correction).
However, these effects largely disappeared after correcting only inverted voxels with a correlation stronger than -0.1.
