==Phase-Mapped Retinotopy, Revisited== | |||
There are some problems with the processing steps noted above. | |||
It is wrong to smooth in the volume, because adjacent voxels in 3-D space may be far apart on the cortical surface and have very different response phases. | |||
The Fourier transform is not optimal, the Hilbert delay may work better. | |||
Ziad has written a retinotopy processing script, | |||
/Volumes/data9/surfaces/scripts/@RetinotopicProc | |||
Which addresses some of these problems. | |||
