> What may NOT be arbitrary, tho, is the Brightness.
I guess the scale is arbitrary. I don't know the scale for fMRI's but I figure they have to pick a scale for when blue becomes green becomes red etc. I figure the scale they use is fairly arbitrary and if you change the scale you would end up with a different looking fMRI. Different colours at different patches.
The colour stuff is interesting. I didn't know all that.
> Changing the brightness not only does not add to the interpretation of, say, a PET scan, it actually introduces a non-existent variable or, rather, a variable indicating the "goodness" or the "badness" implicated by the colors.
I find that very interesting indeed.
:-)> That being said, I have no problem with biases in scientific observations since I don't believe in objectivity -- but you need to acknowledge your biases for what they are if you're going to have any degree of intellectual integrity or honesty.
Yeah. They have implications for how the results are legitimately interpreted.
> As an aside, I always find it a bit amusing that red tends to be assigned to high evergy levels and violet to low energy levels. The physicist in me just wants to giggle at how they got it backwards.I didn't know it was reversed in physics. My knowledge of physics is exhausted from what I've posted about it in this thread. All I know... Is there is math in physics and I'm not so hot at math ;-)
Thanks for your post.
I'm sure I will return to it at some point
(When I look at fMRI's in more detail):-)
