Click here to view the polar-angle map superimposed on a T1-weighted image.

The maps are not corrected for hemodynamic response delay. The eccentricity map is in arbitrary units, and is corrected (partially) for the cortical magnification. The largest eccentricity corresponds to the size of the display (15 degrees).
Voxel size = 1.57 x 1.57 x 2 mm³, Coronal slices, TR = 3000ms.

Voxel size = 3.3 x 3.3 x 3 mm³, Axial slices, TR = 3000ms.
