Two Brain Theory

Post Reply New Topic

Very possibly , I found several vids on that link you offered ,about brain hemisphere differences and did get a little lost watching them. There was 2 women and a male being interviewed , all well credentialed people. They had
Gone into the brains neural plasticity being related to learning abilities of the hemispheres and youthfulness being a developmental time for this thing. But also other methods to potentially increase neural plasticity after you become older .

The video that I provided a link for had 3 men discussing the concept of two individual brains residing in one body.
The one you cited had 2 women and a male discussing a different topic neural plasticity.
This is a very different topic. Neural plasticity is a theory that brains are like plastic. I am not totally convinced this theory is accurate. But it is used by the medical community to try and restore knowledge to some stroke victims. Many people who suffer strokes lose the ability to move their right (foot, arm, leg, hands) or their left (foot, arm, leg, hands). Basically one side or the other. A large amount of effort has been applied trying to fix their condition with mixed results. I am not sure that I believe in this theory. But in my case, my problem from the stroke is very different. I have full arm and leg movement capabilities. What I lost is in my head. I lost my ability to read (but not my ability to write) and most of my memory of words and half my eyesight. I have gained much of this back and am working very hard on the last part MY VISION.

So anyways, I think you probably accidentally cited the wrong weblink.

Went back and watched the video including Alan Alda … and appreciated their discussion on the two lobes potential to struggle for dominance under certain conditions .. but did not find it as informative as some of your earlier video
You have posted . Seemed like they were stating the obvious , of what happens regarding the two lobes .

I agree. That is why I added the following comments to my review:

I would say there are a couple points they are missing.
1. The two halves of the brain can develop a time sharing arrangement. REM sleep is a fairly short period of the 24 hour day, but when one of the brains can move at almost the speed of light, the sharing arrangement works well.
2. Sometimes the two brains do not have a choice in the arrangement. One half of the brain may go offline for a while due to an injury. The other half takes control, otherwise the individual dies. It can be a function of necessity.

It allowed me to highlight some major differences.

Okay , I appreciate your taking. The time to repost this synopsis .Thank you . Think that video could have done more justice to the topic/ concept of split hemispheres .

Some more tidbits from the INTERNET

Dual consciousness is a theoretical concept in neuroscience. It is proposed that it is possible that a person may develop two separate conscious entities within their one brain after undergoing a corpus callosotomy. The idea first began circulating in the neuroscience community after some split-brain patients exhibited the alien hand syndrome, which led some scientists to believe that there must be two separate consciousnesses within the brain's left and right hemispheres in competition with one another once the corpus callosum is severed.

One of the reasons why this theory was developed was due to ALIEN HAND SYNDROME.
Alien hand syndrome, sometimes used synonymously with anarchic hand is a neurological disorder in which the afflicted person's hand appears to take on a mind of its own. Alien hand syndrome has been documented in some split brain patients.

The classic sign of Alien Hand Syndrome is that the affected person cannot control one of their hands. For example, if a split-brain patient with Alien Hand Syndrome is asked to pick up a glass with their right hand, as the right hand moves over to the glass, the left hand will interfere with the action, thwarting the right hand's task. The interference from the left hand is completely out of the control of the patient and is not being done “on purpose”. Affected patients at times cannot control the movements of their hands. Another example included patients unbuttoning a shirt with one hand, and the other hand simultaneously re-buttoning the shirt (although some reported feeling normal after their surgery.

So where does the science on split brain functioning currently stand? A 2020 article (Split-Brain: What We Know Now and Why This is Important for Understanding Consciousness) states:

Does a split-brain harbor a split consciousness or is consciousness unified? The current consensus is that the body of evidence is insufficient to answer this question, and different suggestions are made with respect to how future studies might address this paucity. In addition, it is suggested that the answers might not be a simple yes or no but that intermediate conceptualizations need to be considered.

----------------------------

In other words, the entire subject is still up for debate. From my perspective:
* What happens to a young child who is still in the development phase (under around 12 years old) who experience a severe head injury resulting in brain damage to the left hemisphere?
--Does their brain rewire itself, rearranging duties, for example transitioning responsibility between the right and left hemispheres?
--If that is the case, how does it impact future the individual's brain development. For example, what happens when a child transitions to adulthood around the age of 12 years?

Neurons are the building blocks of the brain. During development, neurons create networks that link to create systems. These systems are how the brain regulates all functions. Brain functions are organized from the most simple to the most complex. The development of these functions is sequential, meaning prior events impact future development.

Brain development in infancy and early childhood lays the foundation for all future development. Neural pathways form at great speed and depend on the repetition of experiences. Experiences teach the brain what to expect and how to respond.

When experiences are traumatic, the pathways getting the most use are those in response to the trauma; this reduces the formation of other pathways needed for adaptive behavior. Trauma in early childhood can result in disrupted attachment, cognitive delays, and impaired emotional regulation. Also, the overdevelopment of certain pathways and the underdevelopment of others can lead to impairment later in life.

By age three, the brain is almost 80% of its adult size; by age five it is 90%. Although this creates a sense of urgency regarding intervention, it is also important to know that the brain has the most plasticity in infancy and early childhood, meaning there is the most opportunity for change. This is both the reason that prolonged trauma in early childhood can be so devastating, but also a window of opportunity for interventions that can alter the brain in positive ways.

In the early years of childhood development, the human brain is still a work in progress. And a traumatic injury can dramatically alter normal childhood development.

I decided to take a different approach and see if a brain injury in childhood can cause Autism/Asperger's Syndrome.

When I was a child, I was knocked unconscious when a large bull struck me and rendered me unconscious. This occurred around age 3 or 4. I weighted about 20 pounds and the bull weighed around 1,000. At that age it is almost like being attacked by a large dinosaur.

So I began a search through the massive sphere of the Internet:

Shaken baby syndrome — also known as abusive head trauma, shaken impact syndrome, inflicted head injury or whiplash shake syndrome — is a serious brain injury resulting from forcefully shaking an infant or toddler.

Survivors of shaken baby syndrome may require lifelong medical care for conditions such as:
-- Partial or total blindness
-- Developmental delays, learning problems or behavior issues
-- Intellectual disability
-- Seizure disorders
-- Cerebral palsy

Here is an interesting word "Cerebral Palsy", I wonder what that is?

Many kids with Cerebral Palsy have at least one co-existing condition:
-- Hearing deficits
-- Vision impairment
-- Seizures
-- Cognitive disability
-- ADHD (Attention Deficit Hyperactivity Disorder)
-- Behavioral, emotional issues
-- Feeding problems and nutritional deficiencies
-- Gastric reflux
-- Constipation
-- Scoliosis
-- Joint problems
-- Sleep disorders

I consider myself an Aspie. With regard to ADHD and Asperger’s, there is a large overlap in symptomology. In my experience, roughly 60-70 percent of children with Asperger’s Syndrome have symptoms which are compatible with an ADHD diagnosis. (Daniel Rosenn, M.D.)

Well it is raining and the water is going over my bridge. My driveway passes through a small creek that becomes a raging river when it rains. I have two 3 foot diameter pipes that passes small quantities of rain water. But if the rainfall is greater than the bridges can handle, my bridge is designed to allow the water to go over the bridge. The bridge has around 300 yards of concrete. It is strong and has survived many floods.

Sounds like it was well designed … used to be when I did projects, that I suspected could be encountering adverse forces . Would think to try to design to better than 150% of tolerance . Been pretty fortunate with many of my so called ad hoc projects.

My wife and I built our own home. We did about 90 percent of the work. It is a unique home. About 10 years ago, tornadoes ripped through our property. They destroyed about a hundred of my trees (greater than 1 foot in diameter). In every direction around the house, I lost trees. But the house stood. I built it well.

Congrats .. something to be said for the extra design and physical work . If ones willing to put in the effort.
Had attempted that with my husband and myself. With a seriously modified cheap o mobile home with several structural reinforcements. Which we did together . On own property but was swindled by my brother with His GF and a devious neighbour ,After 25 yrs .During a critical time when husbands father became very ill. And needed to leave to care for him. Local prosecutors office was associate of devious neighbour. Situation ran out of options resulting in homicide of my late husband. But the structure still stands strong , via Google satellite. Structure also withstood a small tornado . Back in the 1990s

Sorry to hear about the problems you encountered. It was a lot of work to build your own home. But I would do it again if I had to do it over.

A few years ago, my wife decided that we must build a small house for the grandkids when they visit. I thought this didn't make much sense because they are rarely at our house for a visit. But in the end I agreed but under two conditions.
First, the small house must be a log house. I never built one before so it would be a learning experience for me.
Second, the grandkids must help in the construction. It would be an opportunity for them to learn how to build a structure.
They agreed and the small house turned out to be a pretty little playhouse.

It just dawned on me that when I built the playhouse, I recorded it on the internet.

Log Cabin Playhouse

I have to teach the young ones how to do things.

Thank you , went through your entire building process,, it was very thorough. And had good advise about many different points of construction. It was lovely when it was done, am thinking the structure will outlive your children .. big smiles . Solid design, enjoyed the foundation setting process… very much, good thinking with the buckets ..

Thanks
