Re: Contralateral Brain???

[Guest guest]

Connie,

The language dominance is not a wiring issue. The brain selects an

organization, and since the left side is better set up to use the left for

language, most brains go that way. The control of physical functions and

receipt from sensory organs is hard-wired.

The cerebellum does control the ipsilateral sides of the body. Left side

controls left, etc.

wondering, however, are there some people whose right side controls

right body and left brain to left body? I know this is not what we

learn in normal cases, but are there anomalies like with people whose

language center may be on the right, etc. If this is possible, how

could we tell if an individual is like this?

I wanted to share why I asked this question.

All of my family is right-handed. I even tried when I was a kid, to

write left-handed and found it too difficult to pursue. The

neuropsychologist I am working with thought for sure I would be left-

handed or at least ambidextrous (sp?)--my right brain had lots of

activity and my left brain had very low-amplitude waves (all

frequencies) in comparison. I also fit the profile of someone who

is very right-brained.

My sister, the artist, is also right-handed. When her neurosurgeon

was preparing (over weeks) to do brain surgery on her, he did a test

which " froze " sections of her brain to see what functioning she

had. She lost most of her functioning when her right brain

was " frozen " and very little when her left brain was " frozen " , yet

she is strongly right-handed.

I also posed this question to the neuropsychologist I am working

with via e-mail. The following is his response that I thought may

interest some members:

" Two conditions: 1) If the Corpus Callosum (Inter-hemisphere) is

disconnected, same sided strengths are developed. This could lead

to same sided dominance,

2) If Decussation (Brain stem crossover) is incomplete, same sided

dominance could be seen. When there is an intense emotional

(energized) seizure, Autism and other)

quality to a situation bilateral activity may occur lending credence

to " bi-dominance " and possibly same sided dominance. "

I would like to hear some other responses on this if anyone has

any. Thanks!

Dear All

Kaiser in his newsletter Vol 5 No 3 March 2002 addressed issues around dominance. To decide on which hemisphere is language dominant he provided the following visual.

Choose which face is happier? If the right appears happier then the left hemisphere is dominant for language and vice versa.

However the article provides much more detailed discussion of dominance.

I just wanted to clarify my original question about the

contralateral brain. It may have gotten confused because others had

asked about dominance.

I was not asking about dominance. I was asking if there are people

(anomalies) whose right side of the brain controls (for the most

part) the right side of the body ... and left control left. Of

course this is not the case for most people except for a lesser

degree of ipsilateral connections, but are there anomalies?
