Figure 4.

pRFs in the full-field condition for the multifocal and the drifting bars stimulation sequences. pRF size is plotted against pRF eccentricity; voxels are binned in contiguous 0.5° steps. Symbols show medians in each bin for the two stimulus sequences. Continuous lines are linear fits through the data points in each series, weighted by the inverse of their SEM (error bars, smaller than symbol size). This analysis included all voxels successfully fit using both the multifocal and the drifting bars sequence.
