Certain achromatopsic subjects with dysfunctions in this general area seem to lack the feeling of what it is like to see color, its "coloredness," including the "redness" of red.
Schematically, removing r from the top resembles the situation of an achromatopsic patient with a selective Jesion of V8: the bulk of the experience or quale remains intact ([PHI] remains high), but a noticeable feature of its shape collapses (the upset of non-red).
If an achromatopsic subject without the r connections lacks precisely the "redness" of red, whereas a vegetative patient with just the r connections is essentially unconscious, then the redness of red cannot map directly to the mechanism implemented by the r connections.
