is it true that left-handed people have inverted cerebral hemispheres?

Question

(I mean if the hemispheral functions are inverted)

Answer 1

I don't think that is true, left handers have a dominant right hemisphere, or whatever the right side of your brain is called. There is a theory as well that left handedness is an evolutionary step, thousands of years ago it was a survival trait, left handed fighters would have the element of surprise when fighting right handers.

Answer 2

The left handers brain is very different from the right handers brain. As a left hander, I find that there are a vast number of things that I can do and ways that I think that are very different from those of my RH contemporaries. I read on a higher level, I use words when I write that others don't usually use, I write backwards and upside down, which, believe it or not, is much easier than writing "normal". LH people are generally more creative, more intuitive, more emotional, and compassionate. I have had my share of problems with being LH. As a child I lived in Germany, needless to say, I had a teacher that was NOT fond of the left hand and used a ruler on the palm of my hand to "change" my handedness, it DIDN'T work, and I started acting like an "ssa" in class to annoy her. I love being the only person in my family as a dominate lefty, so for those of you who have heard that handedness is hereditary, it's not. Oh, just to be fair, some "scientists" believe that left handedness is due to some sort of brain damage that occured at birth. Whatever! So, that's my two cents.
AND:

Left-brain/right-brain proponents in popular culture will find substantial support for the idea that brain hemispheres are indeed functionally specialized. Moreover, there is significant, repeatable lateralization of the human brain along numerous dimensions. The left and right hemispheres can even perform as independent minds when their intercommunication is severed as in the rare commissurotomy procedure. However, there is significant empirical evidence to refute the idea of hemispheric dominance in the "on again, off again" sense which these proponents presume. Instead researchers continue to affirm the constant, subtle, and profound interplay of the two hemispheres; we do not posses two, limited brains that vie for control, rather we posses an almost transparently unified mind of much greater ability then merely the sum of the two parts.

These are exciting times for all those interesting in the brain and how it works. Still, there are so many questions, seemingly contradictory experimental results, and hyperbole. The truth is, contrary to pop-psychology, we simply don't understand enough about cerebral dominance, brain lateralization, the causes and effects of left/mixed handedness, and how these things interact, to be able to make short, quick, easy-to-digest, blanket statements. It's even a little sad, because the truth is so much more profound, exciting, and interesting

Answer 3

Among the right handed people:
99% have dominant left hemisphere and 1% have dominant right hemisphere.

Among the left haned people:
85% have dominant left hemisphere and 15% have dominant right hemisphere.

Left handed people are neither dumber nor smarter than their right-handed counterparts. IQ has nothing to do with cerebral dominance. If the motor (i.e., part that moves the limbs) function of your brain is dominant on one side, that does not necessarily mean that the other functions (i.e., cognitive, etc) are also dominant on the same side. You many not be aware of this, but apart from a dominant hand, you (and I, and all the rest of the world) also have a dominant eye and a dominant ear. These things don't have a bearing on intellectual or creative abilities (or disabilities) of a person.

Answer 4

no of course not. it is true that brain functions are different in the left and right hemispheres. being left handed, being a recessive trait doesn't mean that cerebral hemispheres are already inverted. It only means that the brain functions more efficiently on the other hemisphere.

Answer 5

They dont' REALLY have inverted hemispheres. What happens is that there is a tissue (like a cable) that joins the brain's hemispheres, but this "cable" is like an X, so the left hemisphere is connected to the right part of your body and the right to the left. This happens in all vertebrates. Because right-handed people use more the right part of their bodies, that part of the brain is more active. Anatomically, there is no difference between them.

Answer 6

yes it is true that for a left handed person the right side of the brain is the dominant hemisphere. But it has nothing to worry about they r as sane as a person should be.

Answer 7

yes the left handers have the right side cerebral hemisphere functional
and i am also a left hander in fact i write with both hands but my right cerebral hemisphere is more developed and left handers are also good artists as i am

Answer 8

There is scientific evidence to suggest that some left-handed individuals are a surviving "mirror-image" twin. The non-surviving (probably right-handed ) twin succumbed to the "disappearing twin" syndrome whereby one twin dies in-utero and is re-absorbed into the mother. Mirror image twins can have internal organs, such as the heart, on opposite sides of the body. Is there such a thing as an inverted brain?

Answer 9

If you mean is a left handers brain right side dominant, yes. Also explains why lefties are often very creative. Right handed people are left lobe dominant being generally more logical.

Answer 10

i doubt it.i am a lefty.explain inverted cerebral hemisphere to me at [e-mail] or im me at [e-mail]
