Disparity Processing

Positron emission tomographic methods have been used to identify visual areas involved in the processing of small horizontal disparities. In one such study, subjects were presented either random noise patterns or Julesz-type stereograms. The difference in the regional blood flow patterns was taken to indicate regions of cortex involved in the analysis of the stereogram patterns. The resultant regional blood flow patterns were then mapped onto the corresponding anatomical sections derived from magnetic resonance imaging. Statistically significant cortical activation was observed over a large region of occipital cortex that involves areas 17, 18, and 19.
