Stereo pair smooth depth reversal

What is the perception of a stereo pair if the disparities of a semi-natural image are smoothly changed, such that the stereoscopic depth of every feature is reversed, with far things becoming near and near things far?

A primatologist (SUNY?, I lost his name and address) sent an interesting photo of a dissected tarsier brain and eye. He was looking for a comparable image of human vision hardware. I am working on animations of various brain systems, so I put together of rendering of roughly the same parts:

Euglena Academy's fall program is out, see below. I'm going to try to get to a couple of the Cozmic Pizza presentations.

Euglena Academy is an independent, college-level school for adults (18+) in Eugene, Oregon offers scientifically rigorous classes (beginning & advanced) and workshops about systems sciences (also known as complexity). 

Human brain animations

Resources for, and animations of, a human brain. These are primarily surface renderings from MRI volume data. Space Software was used for most manipulation and rendering.

Description of remove_background_peak_image.m (MATLAB)

See attached code file, remove_background_peak_image.m.

[ vPeak fFWHM_range imZeroBackground ] = remove_background_peak_image( strInputFilename, fFWHM, bShow )

USAGE:  [ vPeak fFWHM_range imZeroBackground ] = remove_background_peak_image( 'test_remove_background.png', 1.5, true );

Test renderings of the P22 virion EMD-1220 data set

Central slice. Note the needle and lead dsDNA detail (near center), and more than four concentric shells through the horizontal plane at center of capsid.
