John Sundsten's group out at the University of Washington Department of
Biological Structure puts out a laserdisc of 3D brain animations that have
been reconstructed from an actual human brain. The images are phenomenal.
Probably the best you will find anywhere. I believe their ftp site is
ftp.biostruc.washington.edu I don't have their phone number at hand, but
if you are interested, I can dig it up.
