Two Brain Theory

Back to the drawing board----According to the Internet

Longitudinal callosal fascicles, or Probst bundles, are aberrant bundles of axons that run in a front-back (antero-posterior) direction rather than a left-right direction between the cerebral hemispheres. They are characteristic of patients with agenesis of the corpus callosum and are due to failure of the callosally-projecting neurons (mostly layer 2/3 pyramidal neurons) to extend axons across the midline and therefore form the corpus callosum. The inability of these axons to cross the midline results in anomalous axonal guidance and front-to-back projections within each hemisphere, rather than connecting between the hemispheres in the normal corpus callosum. (Source: Wikipedia)

Well that explains a lot. Not really ! !! I am a stroke victim and my brain feels pain when I read this.
So essentially in a Probst Bundles the two halves of the brain are not connected together like in normal brains. Instead the two sides form their own internal linkage causing the two sides to function separately.

But it gives me a new duplicate word to look up - Longitudinal Callosal Fascicles.

The corpus callosum is the major white matter tract that connects and right and left hemisphere. It allows for cross communication between the two hemispheres. In certain rare developmental disorders, a person may be born with agenesis of the corpus callosum. Probst bundles are a diagnostic sign that indicates agenesis of the corpus callosum. Instead of a white matter tract that spans the medial-lateral axis, Probst bundles appear to run parallel to the interhemispheric fissure, the midline where the two hemispheres separate. Probst bundles can be seen using magnetic resonance imaging (MRI) or diffusion tensor imaging (DTI). In scans, agenesis of the corpus callosum produces a “racing car” shape.

I woke up this morning and opened my computer. It didn't want to come on. So I tried to restart it. But then this came up. So I read it and realized that it was something that I wrote. Hmmm, this is strange. Why did it show up on my screen now. So I thought I would send it out on the World Wide Web.

So take this as an intermission at the movie theater:

We live in a Great Ice Age called the Pleistocene Epoch which began around 2.58 million years ago and will continue for several million years into the future. During an Ice Age, the Earth cycles between cold Glacial periods that last for approximately 100,000 years and warm Interglacial periods that last for approximately 10,000 years. An Interglacial is a short warming period where the Earth thaws between the icy grips of the glacial periods. The present interglacial period (the Holocene) began approximately 14,000 years ago.

ICE AGE TRANSITIONS FOR PAST 600,000 YEARS
Holocene (interglacial, 14,000 years ago - present)
Wisconsinan/Weichsel (or Vistula) (glacial period, 70,000 – 14,000 years ago)
Sangamon/Eem (interglacial, 130,000 – 70,000 years ago)
Illinoian/Saale (glacial, 180,000 – 130,000 years ago)
Yarmouth/Holstein (interglacial, 230,000 – 180,000 years ago)
Kansan/Elster (glacial, 300,000 – 230,000 years ago)
Aftonian/Cromer (interglacial, 330,000 – 300,000 years ago)
Nebraskan/Gunz (glacial, 470,000 – 330,000 years ago)
Waalian (interglacial, 540,000 – 470,000 years ago)
Donau II (glacial, 550,000 – 540,000 years ago)
Tiglian (interglacial, 585,000 – 550,000 years ago)
Donau I (glacial, 600,000 – 585,000 years ago)

There is nothing to assume that our planet has exited the Pleistocene Epoch. The temperatures have not recovered to the pre-Ice Age temperatures. Generally there is nothing to fear from warmer temperatures. The warmer temperatures produce a period with great expansion of life and diversity of life on the planet. The real danger is a return to the ice age conditions. All you have to do is compare the quantity of species and diversity of species from the polar regions to that of the equatorial regions to understand the danger. Ice age conditions represent a starved condition for the planet.

So the present interglacial period began about 14,000 years ago and they generally last around 10,000 years. And all these interglacial/glacial periods are driven by natural climate change. So it sounds like we are due for the next glacial period. There are some that assume that man has influenced climate to a greater extent than nature. That is a fairly substantial assumption. And if they are wrong, then we are currently on the brink of reentering another glacial period.

O.K. BREAK TIME OVER. BACK TO WORK.

When I was a kid, we were living in the Pleistocene, too, believe it or not. The Holocene was created, I believe, in the 1970s.

Gulp….. did someone say Ice Age .. ? .. yikes .. glaciers melting ?

I spent 2 hours writing about the different types of humans yesterday and then the computer decided to destroy it. I spent a half hour trying to find it and restore it but I am afraid the only fragments that are left are in my fractured mind.

At this point, I am going to switch directions on my train of thought.
There are two types of adult humans. There are the majority who have a fully connected integrated left/right brain structure. And there are individuals who have two separated fully independent brains. I fit the secondary category and would describe myself as:

There are two halves to the human brains, one on our left side (primary) and the other on the right side (secondary). At the age of 3 or 4 years old, I was attacked by a massive bull (remember I am a wee little one at the time). I almost died. But when I slowly started to come back to life, it was my second brain (the right side) that returned. In other words, the two halves of my brain switched places. Eventually the side that was damaged came back and then became my secondary brain. And life was good. But then I entered the years when young boys become young men and my world fell apart. I was subjected to 3 years of constant mental and physical torture from my classmates. They almost destroyed me. Because at a young age my brain sustained damage, I never was able to make the transition into adulthood. (the image on the left is the real me, even though I am now 73 years old inside I am still that young little boy) Because of the damage from the massive bull attack, my right and left sides of the brain never created the interconnection that ties these two halves together. A left-right direction between the cerebral hemispheres never developed and in its place a different type of structure called a probst bundles was formed. This interconnecting region of the brain normally develops around age 10-12 in males. As a result, I have two very independent brains.

In other words, my primary brain is now my secondary brain and only in the deepest stages of sleep, called REM sleep does it come out to play. But it is a very fast brain, moving almost at the speed of light. And in my opinion one of the smartest brains in the world. And I feel that we have developed a friendship together.

Jill Bolte Taylor suffered a massive stroke at the age of around 35 years. In her book "My Stroke of Insight", she describes what happened to her. Her right and left hemispheres changed places because of the damage from her stroke and as a result she became a totally different person. She wrote in her book, "that at the core of my right hemisphere consciousness is a character that is directly connected to the expression of peace, love, joy, and compassion in the world."[/b]

She has correctly articulated my inner self, but then my transition into adulthood was extremely painful. But I endured. And then in the 9th grade, I took a class in Speed Reading. This opened up the world of books to me and my mind began to grow. At the end of high school my classmates considered me the class generous. I went on to college, earning a degree in Physics at UCLA and then worked for 4 decades as a scientist and engineer. But unlike many, my mind grew like a rocketship and never stopped developing. I became Peter Pan.

When I think back of all the wild and interesting things that I have done in my life, I am totally amazed.

Who is Peter Pan?

Peter is a boy who never grew up. He lives in a mystical place called Never Never Land. Peter has a nonchalant, devil-may-care attitude, and is fearlessly cocky when it comes to putting himself in danger. When Peter thought he was going to die on Marooners' Rock, he felt scared, yet he felt only one shudder. With this blithe attitude, he says, "To die will be an awfully big adventure".

The Lost Boys are Peter Pan's companions in Never Never Land.

Peter Pan and the Lost Boys are different from other boys who inhabit the real world.

It is the reason why I see the similarity between Peter Pan and the Lost Boys and the inhabitants of WRONG PLANET. We feel like we live in a very strange world. Like something is a little off. Somehow we do not quite fit in. We are misunderstood.

You have a gift for making what appears to be very accurate synopsis of situations around WP
Members . It is very good that you made the best of your split brain situation into your adulthood …

I feel like as my brain developed more in my twenties, I went from a much more artistic person, able to draw things easily from imagination, write poetry, etc., to a hyper-rational type. Even my art changed and now I'm able to draw things extraordinarily well from observation but my ability to draw from imagination has been snuffed out and is of great frustration to me. Something dramatically switched in my mid-twenties and it feels like my brain became a vice. It's something I simultaneously love, also being a neuroscientist, but I miss being more creative too. I used to write poetry and that just disappeared around that time too.

I always joke that I may eventually get it all back if I develop Alzheimer's and my frontal cortex loosens its grip. (Funny/not funny)

My mother developed Alzheimer's before she passed away. I guess I have a different interpretation of Alzheimer's. As she grew old, she lost a lot of her senses. Her vision went downhill and she almost became blind. Her hearing also suffered. All her senses suffered from the effects of old age. So when she heard someone talking, she missed many of the words. And as a result, her mind filled in the blank, the words she missed. The same thing happened to her vision. As a result she began to live in an imaginary world.

Now I am going to try and explain something - A MAJOR DISCONNECT

There is a big difference between WHO I AM and WHO THE ADULT WORLD THINKS I AM.

When I grew up, I never made the transition from childhood to adulthood. I am 73 years old but I am still a young child. Due to a massive brain injury at the age of 3 or 4, I became different. My right hemisphere of my brain switched places with my left hemisphere. So I grew up a child living with other children and life was good. That was until most people make the transition into adulthood. At around age 10-12 the two separate halves of the brain link together and they enter adulthood. Well in my case, they didn't. And I remained a child living in a world of adults. And that is where the problem arose.

I suspect due to my childhood injury that I am missing my Corpus Callosum, a connection that normally forms around age 10-12 that causes the two halves of the brain to join together. As a result I developed a different structure in my brain called a Probst bundles. This is a unique connection that is radically different from normal human brains.

As Jill Bolte Taylor explained "at the core of my right hemisphere consciousness is a character that is directly connected to the expression of peace, love, joy, and compassion in the world." In the world of adult males, this trait is almost like signing a death warrant.

But then almost by chance, my brain took off like a rocketship. I became a little like Mr. Spock in Star Trek. I became Peter Pan, the boy who never grows up.

The eternal child…. Has great benefits, I think , your creativity and imagination might be less likely to be impeded by adulthood .

The winter storm struck. We received around 5 inches of snow. But the beginning of the storm was freezing rain and ice. I spent the morning cleaning off my driveway. It is around 1,000 feet, so it was a little work.

As kraftiekortie wrote "It's rather like re-learning how to ride a bike."

I think you are right. I was able to get the large gasoline powered snow blower (magical ice crusher and destroyer machine) working. I guess the skill is still locked somewhere inside me. And away I went for several hours, engaged in a battle against the sleet and snow.

So who is this character called Peter Pan?

Well, it was really cold this morning. It was 1.4 degrees F or -17 degrees C. But the sun came up and my small piece of the world is beginning to warm up. Soon it will be 2 degrees.

My other brain, my REM (rapid eye movement) brain was roaring last night. I am glad to see you back. It has been almost 10 months and I was beginning to get worried about you.

We cleaned off our driveway after the snow storm before the temperatures dropped like a red brick.
Red Brick - what does that mean????? No, I really meant to say Lead Brick.
O.K. correction made. Must be some kind of word rhyming flaw after experiencing a stroke.

Word blurbs …. But it sounded right …. Maybe not a creative stretch, I go through is misreading words on signs to make them sound phonetically different , and turn the meaning into something different. Childhood habit .
Then when very small and out of interesting reading material . Would proof read magazines , that eventually would be destined for the trash. And cross out words in the articles in certain sentences, to create new meanings. To the entire sentence, and still try to keep it in context with the rest of the paragraph.
