Quote:Cortical colour blindness is caused by brain damage to the ventro-medial occipital and temporal lobes. A possible explanation is that the pathway responsible for transmitting information about wavelength and its subsequent elaboration as colour has been destroyed at the cortical level. However, several signs of chromatic processing persist in an achromatopsic subject who, despite his inability to tell colours apart, can still detect chromatic borders, perceive shape from colour, and discriminate the direction in which a striped pattern moves when the determination of direction requires the viewer to ‘know’ which stripes have a particular colour. Perhaps only the information about wavelength that leads to conscious awareness of colour has been destroyed.

Would it be useful to an organism to "know" the color of objects in its environment? Their shape? Their relative location?
There are lots of document effects like the one you are talking about: loss of left-right integration in split-brain experiments, loss of ability to recognize faces, etc., that result from damage to very specific brain parts.

Qualia may not be "advantageous" (I would disagree but give it to you for the sake of discussion).....but all of the hardware that seems to be -at least- associated -is- advantageous. It could be a bundle deal, or perhaps not - we don't know. We aren't required to know in order to attempt a scientific explanation.
No doubt the functions are highly advantageous. However, IF qualia is only the subjective experience of brain functions, then qualia isn't actually doing anything.
