Two Brain Theory

Post Reply New Topic

Okay , if brains do not operate as different hemispheres, then why are people left or right hand dominant.?
Inversely if both hemispheres operate in unison then why isn’t every one abidexterous. And myself , have found that
Many tasks would get delegated automatically to certain tasks, To throw a ball, it had to be done right handed.
But to write something or operate a door handle my body prefers my left hand .Am told , I was left handed.

According to Wikipedia

Other studies have also linked possible correlations between corpus callosum malformation and autism spectrum disorders.

-----------------------------------
According to an article on Medical News Today:

The corpus callosum connects the left side of the brain to the right side, each side being known as a hemisphere. The connection allows information to pass between the two halves.

Corpus callosum is Latin for “tough body,” and the corpus callosum is the largest connective pathway in the brain, being made up of more than 200 million nerve fibers.

Very occasionally, a person will be born without a corpus callosum. This is known as agenesis of the corpus callosum, and it causes a wide variety of physical and behavioral symptoms.

Typically, the corpus callosum will form in the brain between 12 and 16 weeks after conception and near the end of the first trimester of pregnancy.

It will continue to develop throughout childhood. By the time a child is 12 years old, their corpus callosum will have finished developing. It will then remain unchanged into adulthood and throughout the rest of their life.

Sorry. It is a little too late in the evening for me to answer this as well as I would like. But in one article:

Handedness in children with autism spectrum disorders

it states:

Rightward-asymmetry in regions of corpus callosum has been reported to correlate with symptoms severity in ASD (autism spectrum disorders)[
Children with ASD had more left-handedness (χ2(2) = 12.54, P = 0.002).

Thank you very much for that article Jimmy m. I enjoyed it very much . And yes still even after all these years my brain still does alittle echocolia, on and off. . Took a long time to stifle it.

Clearly only one half went to college.

(Greedy colleges will start charging tuition for both halves)

O.K. I hope I didn't speak too soon. The primary issue is not whether you are right handed or left handed but rather whether you are dual handed, able to use both your right and left hand. Rather than just one hand.

There was a response to an article published in 2018 that is interesting. It reads:

Letter to the editor in response to Howard Kushner's claims that our data on non-right-handedness within the autism spectrum disorder were organized, by sleight of hand, so they would give a significant result that would support our desired conclusion. Here, we have re-categorized our data, and present evidence that there are indeed more left-handers within the ASD. Furthermore, we refute claims that we have misinterpreted our results in order to conclude about a causal link between left-handedness and ASD, and highlight our original suggestion that mixed-handedness, more specifically unclear handedness, is the bigger problem, and that our findings of a total 60% non-right-handedness was the more interesting finding.

So I put it to a test. I wrote the letters in my right hand and then my left hand. The letters were almost the same. I could write the letters faster using my right hand but that was the only difference. With practice I might even be able to get the two speeds to be the same. So I am dual handed or as the article refers to this as
mixed-handedness, more specifically unclear handedness.

Thank you for those article citations, made for a very interesting post Jimmy m made .
Found myself wandering around in the National Institute’s of Medicine website.

The handedness issue just potentially validates my professionals diagnosis of autism .Especially considering mixed handedness .
Interesting Jimmy m , do you actually write legibly with both hands?

Interesting question. I believe the answer is yes. But there are different forms of writing. These are Printed and Cursive. This is the difference:

Printed is that style of handwriting in which the letters are written separately while forming a word.
Cursive is the writing style in which letters are joined together to make a meaningful word.

I was in the military in communications for 6 years. So when you send messages they are always printed, because the letters can be read perfectly. Most children start by printing and then eventually transition to cursive. I can do both forms of writing and I think most people are able to do both.

Okay Jimmy m which of your hands writes which. Way. Or do both write both ways ..?
And I understood about printed and cursive . With my left disabled dominant hand , if I have lots of time , I can get it to write very slowly . But since the accident ,hand use is very very limited of that hand. So not by choice,
Am now right handed since the wreck I was in . But can manipulate my writing styles , to about 5 different ones.
But when my left hand was working , could do almost ten different styles of. Writing.

I am right handed. That is the normal way I write.

In a slightly different topic. I had a stroke but that did not affect my ability to write. But many people have strokes and it will almost parallelize one side of their body. Either their left hand and leg or their right hand and leg. This can make their lives very difficult, especially if the side of the hand they normally write with is parallelized.

Head injury from accident way back when had me unresponsive for many weeks then as I woke up , was paralyzed completely for more weeks then right side came back on line, about 90 days later parts of the left side, started to return . Little by little notwithstanding. Permanent nervous system damage to the spine controlling left hand , forearm, sympathetic and parasympathetic on the left side. Very long recovery and rehab. At least to the level am at now. Many many years later. Relearning writing was quite a challenge eventually .

Jakki ----Sorry to hear that you went through this. Hope you can get back to normal.

Thank you very much Jimmy m many neurologists have told me that, had gotten back as much use of my body that I was going to get, but as Aspie naïveté allowed made adjustments to my mental state , during time of recovery.
And in spite of real life disabilities had stopped thinking of myself as disabled within the 2nd year of rehab.
Was even masking my disabilities, besides my social masking ,but my Autism was still a issue.

All I can say is that Aspies are different. In a way, we have special powers. We can move mountains but we have to go where no man (or woman) has gone before and do the impossible.

When you encounter limiting situations concerning your own body / physical abilities, it help me to think how would I have handled this situation, if I had been borne with these physical limitations. And approach everything from that point of view. Then improvise as necessary .

I have found out that Jill Bolte Taylor has published a second book. So I ordered a copy of the book. She also did a TED Video. So here is a link. So if you are interested in TWO BRAIN THEORY, this is essential.
