Volumetric brain oblique. Rendered on a Pixar Image Computer, circa 1987. This is a schizophrenic male, we did work on mapping EEG data onto the volumetric data, the first ‘functional’ combinational imaging that I am aware of. This all pre-fMRI.
This particular image is from the Pixar Image Computer’s CHAP Volumes software, which I worked on when I first got to Pixar in ’87.
