Striate pattern matrices from sighted subjects. A, Within- and between-hemisphere striate pattern matrices. Following a Fisher's r-to-z transformation, the individual pattern matrices from 22 sighted subjects were averaged. The effect of digital image structure in the within-hemisphere modeled and removed from both this representation and in B. B, Corticocortico receptive field depictions derived from the pattern matrices. In the first row, correlation data depicted in A are replotted for the receptive field view by change (in millimeters of cortex) along the AP and SI dimensions. The second row represents the 2D Gaussian fit to these data. The third row represents the absolute value of the residuals of the model fits to the data. Minimal residual structure is seen, supporting the validity of the model.
