Myth
Is this really true? It has the feel of a myth. This site explains in a little more detail:

- Interesting article. It seems it is arguing that "the brain is a marvelously complex organ that its function cannot be quickly and easily pigeonholed", which I would completely agree with and which is supported by neuroscience. The dichotomy between the hemispheres (artsy on the right and logical on the left) is just a pop psychology simplification of the matter (it's more than a simplification, this sort of simplification is just flat-out wrong, yet the story is told anyway because a lot of people are inclined to believe in it, I guess).

- If it's flat-out wrong then it shouldn't be in the article... - Omegatron 14:18, Nov 1, 2004 (UTC)
Animals
If this difference in function between the two hemispheres is true, is it the same for all cultures and races? Is it present in animals too? I am wondering about right- and left-handed, reading left-to-right, etc. - Omegatron 14:18, Nov 1, 2004 (UTC)
Mirror images
"Each hemisphere is a mirror image of the other"
To what degree? Just in general shape? Are the folds on one side mirrored by the other? - Omegatron 13:44, May 20, 2004 (UTC)
- Where is that quote from? Each hemisphere is not an exact mirror image. There are "subtle" differences. For example, the lateral sulcus is often longer in the left hemisphere than the right. About the folds, or sulci, these are not mirrored "exactly", but there are variations. The best thing to do is try to find pics of a human brain and compare the differences for yourself, because I'm not doing such a great job explaining what the differences are. Again, it's a subtle thing, and you would have to look at the patterns of sulci in each hemisphere closely, but you'll see that there are definitely differences. I'm not sure about differences in size between the two hemispheres. Cerebral 17:56, 22 May 2004 (UTC)
- It is the last sentence of the first paragraph. Please clarify which parts are mirror images and which are not. You seem to know a lot on the subject. Anything more you want to add is welcome. - Omegatron 16:29, May 23, 2004 (UTC)
Not exact mirror images. There are some slight differences in overall shape between the two sides. Carter "Mapping the Mind" has some details on this. --Pfafrich 09:10, 2 Jun 2005 (UTC)
