Additional information for the dataset:
ppt = participant code (16: SC01, ... , SC08, CC01, ... , CC08)
group = group (2: 1 = sighted control, 2 = cataract reversal)
poi = patch of interest of a vertex (6: V1d, V1v, V2d, V2v, V3d, V3v)
hemisphere = hemisphere (2: LH, RH)
VertexID = ID of vertex in standardized mesh
eccbin = eccbin of the vertex, according to "ecc" column
1: 0.5° – 1.5°, 2: 1.5° 17 - 2.5°, 3: 2.5° - 3.5°, 4: 3.5° - 4.5°, 5: 4.5° - 5.5°, 6: 5.5° - 6.61°
eccfine = finer bins of eccentricity for linear model
0.5° - 1°, 1° - 1.5°, 1.5° - 2°, 2° - 2.5°, 2.5° - 3°, 3° - 3.5°, 3.5° 19 - 4°, 4° - 4.5°, 4.5° - 5°, 5° - 5.5°, 5.5° - 6°, 6°- 6.61°
pois.dv = patch of interest across dorsal and ventral stream (3: V1, V2, V3)
X/Y/Z = coordinates of vertex
R = square root of the explained variance of the best fitting pRF model per vertex, used as threshold
p.value.R = associated p-value
X = x location of the pRF model assigned to a vertex (negative x values [left visual field] on right hemisphere)
p.value.X = associated p-value
Y = y location of the pRF model assigned to a vertex (negative y values [lower visual field] dorsally)
p.value.y = associated p-value
s = receptive field size of the pRF model assigned to a vertex
p.value.s = associated p-value
ecc = eccentricity of the pRF model assigned to a vertex (in degrees of visual angle) obtained by applying the equation ecc = sqrt(x2 + y2) at each vertex
p.value.ecc = associated p-value
PolarAngle = polar angle of the pRF model assigned to a vertex; estimates of the location in polar coordinates;
the calculated angle α is expressed relativ to the positive (right pointing) x axis and is simply
obtained by applying the equation α = atan2(-y, x) at each vertex.
p.value.PA = associated p-value
CMF = cortical magnification factor [mm/deg] of vertex, derived by dividing the vertex mesh distance by the vertex-to-vertex pRF xy coordinates distance
(in visual field) for neighboring voxels with R > 0.1 and normalizing it by the number of vertices
p.value.CMF = associated p-value
logMAR = Snellen visual acuity measurement in logarithm of the minimum angle of resolution assessed with the FrACT test
vernier = Vernier acuity values in arcsec assessed with the FrACT test
