Abstract:

Stereo images are highly redundant; the left and right
frames of typical  scenes are  very similar. We explore the consequences
of the hypothesis that cortical cells --- in addition to their
multiscale coding strategies (Li and Atick 1994a) --- are concerned with
reducing binocular redundancy due to correlations between the two eyes.
We derive the most efficient coding strategies that achieve
binocular decorrelation. It is shown that multiscale coding combined
with a binocular decorrelation strategy  leads to a rich diversity
of cell types. In particular, the theory predicts monocular/binocular cells
as well as a family of disparity selective cells, among which one can identify
cells that are tuned-zero-excitatory, near, far, and tuned inhibitory.
The theory also predicts  correlations between
ocular dominance, cell size, orientation, and disparity selectivities.
Consequences on cortical ocular dominance column formation from
abnormal developmental conditions such as strabismus and monocular
eye closure are also predicted.
These findings are compared with physiological measurements.
