After spending several weeks talking about how our other parts of the brain trick our I-function, we come back to the more I-function related dicussion this time, it seems. I'm really interested in the case study about patients with visual field deficits. So, they can't see things with certain part of the retina because their I-function fails to acknowledge some of the brain activities, but they can still point out the direction of the light quite accurately because the other boxes in their brain are still working. This result is very intersting, and it actually confuses me. I always think pointing the direction with our hands mainly involves our I-function, but now I'm not so sure. After all, how can those patients use their I-function to point out the light correctly, when their I-function is not even aware of the light? So maybe pointing our hand to something doesn't require the presence of I-function?
