From the main author: If you look at functional studies, the left of the brain is more for logical thinking, the right of the brain is for more intuitive thinking.
I was under the impression that this left brain/right brain theory had been debunked by functional imagery.
- Semaphor 13y agoI'm not sure, I think only the theory that some people are left or right-brained has been debunked. And that there is a strict separation of concerns. IIRC stuff like language processing is still >50% done in the left brain half. But I can't find any relevant studies I'd understand on Google Scholar right now so I might be wrong. And as I'm a layman take this with a grain (or more) of salt ;)
- pygy_ 13y agoLanguage processing is indeed often lateralized (symbolic interpretation left, intonation right, in (most) right-handed people[0]), and other specific tasks are also lateralized, but I don't think you can generalize it like she does. I do have a background in neuroscience (I did research on headache physiology a few years ago), but I'm not too familiar with functional imaging. -- [0] Handedness is a strange thing. The gene that governs it has two alleles. One is dominant, and causes right-handedness. The recissive one, doesn't necessarily cause left-handedness. Handedness is people with two recessive genes is random, roughly 50/50 (a bit less for each, since it can also make one ambidextrous). The clockwise or counter-clockwise rotation of the main cowlick is also governed by the same gene, in the same fashion, AFAIK, independently (the dominant gene makes the cowlick turn clockwise).
