Receptive field sizes as a function of the eccentricity of their centers. Only non-vague (moderate and brisk) units in penetrations showing clear reversals of RF progression were included in the analysis. Straight lines are linear regressions for the two classes of units. The eccentricities were translated from distance on the tangent screen to the view angle from area centralis and the receptive field sizes were calculated as the square root of the area of the ellipses used to model the receptive fields. Receptive field sizes increase with eccentricity in both maps, and receptive fields in the dorsal map were slightly larger than receptive fields in the ventral map at comparable eccentricities.
