Figure 2.

Normal versus dichoptic presentations of a Mondrian and a single target area derived from it. The visual brain has been schematically divided into three parts: two monocular, where neurons are driven by one of the two eyes, and one binocular, where neurons are driven by both eyes. Under normal binocular viewing, light information from both the Mondrian and the single patch (target) are available to the monocularly and to the binocularly driven parts of the brain. This scenario is not the case with dichoptic presentation, where each monocular channel contains input from either the Mondrian or the target, with the two inputs coming together after the emergence of binocularly driven neurons in the cortex. (This figure is an illustrative diagram and does not contain the original stimuli used.)
