Finding a sensitive neuron

The argument here is that the 'path' to these sensitive neurons is 'open' in the case of the globally correct match but not for the incorrect match. In McKee et al's experiment, whether this path is open or not depends on the match the participant makes (the depth plane the participant perceives) even when the retinal stimulus is identical. This means that the path to the sensitive neuron must be determined by the internal, 'motivational' portion of the sensory+motivational context, $\vec{t}$. The path, as before, is a set of Voronoi cells that end up at a different Voronoi cell depending on the global match. When this match is in the fixation plane, the current sensory+motivational context, $\vec{r}$, can be moved from one Voronoi cell to another according to the firing rate of a disparity-tuned cell that is sensitive to disparities close to zero. But when the participant sees the alternative wallpaper plane (false match), the rest of the context $\vec{r}$ puts it in quite a different Voronoi cell and here the firing rate of the same disparity-tuned cell makes no difference to the perception (i.e. it does not move $\vec{r}$ from one Voronoi cell to another).
