Partial blindness and brain hemispheres?

[kubikub]

I saw a thread recently that mentioned left-handedness being linked to artistic proclivities and right-brained functions. I haven't done any research to look into this further (it's almost my bedtime and would be getting very little sleep if I started now) but I had a fun little thought I wanted to share-- what if losing an eye would beget a realignment within the 'dominant' hemispheres of one's brain. Our perception of the world is very much linked to our sight, so I can see it being vaguely plausible that, having lost one side of our vision, we would then view the world through the filter of a single hemisphere's leanings.

I remember hearing once something about how we process sounds through each ear, and that we tend to understand things like directions better when told to the right side of ourselves, and feel greater emotional impact with things told to our left. Somewhat related.

Of course, I understand very little of the actual wiring behind the optic nerves so this could be (and probably is) completely unfounded. But it's late and it's something to think about.

Sight is a pretty hard concept. As you can tell from the diagragm, it is a very convoluted pathway. To start you off, the only way to lose sight in a whole eye is a lesion to the optic nerve itself(black line on the left with the number 1 next to it represents such a lesion, and the greying of the entire left eye on the right with the number 1 next to it). So, I guess you can google optic nerve lesions and see if there is any information on the topic. I, personally, have never come across any but I hate the eye so its not a topic I have researched much.

An interesting notion K. I don't know much about sight but I am loosing my hearing in one ear. It makes sound location a real bitch. It's interesting to learn that you handle information differently with each ear. I haven't noticed much difference but the hearing loss is only partial in that ear and it has been happening gradually for a number of years.
