Do people with brains split apart, are their souls divided into two different halves?

The answer to this question may put an end to idealism.

perhaps the most complex machine in the universe. It consists of two hemispheres, each hemisphere divided into many different modules. Fortunately, all these individual modules do not work autonomously. They must be closely linked, harmoniously coordinated to create and control a single organism: you.

But what if we destroy this harmony? When some modules start to break up with the rest of the brain, is the person inside you also divided into many people?

Interestingly and strangely, this is not an idle question. For some people, that is the reality faced. These patients must have surgery to remove the left brain and right brain. They are nicknamed 'people with split brains'.

As for philosophy, studying these patients is also very important. If scientists can prove that when the brain is separated, '' inside them also split apart, then matter is what determines consciousness. Materialism will win and in fact there is no soul inside us.

The brain is probably the most complex machine in the universe.

Do people with separated brains, their "souls " split into two different people?
We are saying people 'brain split'. They are patients with persistent and dangerous seizures. Doctors are forced to cut off the bottle (corpus callosum) , the signaling pathway between their two hemispheres.

Bottle ablation effectively prevents seizure signals from passing from the hemisphere to the other half. But without the bottle body system, it also means that the two hemispheres have almost no other means to exchange information.

So, what happens to people with 'brain splitting' ? When the two hemispheres are no longer in sync, will you still be a good friend and will turn into two people with different actions?

Roger Sperry and Michael Gazzaniga, two neuroscientists, have been investigating this issue since the 1960s and 1970s. They have found amazing data showing that when a person is separated from the brain, they are will also split into sections.

Sperry won the Nobel Prize in Medicine for his work in 1981.

But how do researchers prove that brain splitting has created two different people, each one controlled by a hemisphere? They conducted a smart test to look at the flow of visual signals into the brain.

When the corpus callosum is removed, the two hemispheres of the brain lose contact with each other.

We know that both eyes send visual information about the brain hemispheres. But the flow of information is quite complicated. When you look at a point, everything on the left side of that point (the left visual field) is handled by the right hemisphere. And conversely, everything to the right of the point (the right visual field) is handled by the left hemisphere.

In addition, the left hemisphere controls the right side of the body (right leg, right hand .) and language output. While the right hemisphere controls the left body (left leg, left hand .) and cannot control us.

In my experiment, when Sperry and Gazzaniga gave an image to the school on the right side of a "brain- torn " patient , everything happened normally. He said he saw these pictures. Meaning the left hemisphere sees the image and it says it sees the image.

The experimental hours are repeated with the right hemisphere of the brain, the hemisphere cannot speak because it does not control the language. Scientists put images on the school side of the left side of the 'brain split' , the patient said he saw nothing.

However, at the same time his left hand drew the displayed image. When asked why his left hand did so, the patient seemed confused, and answered that he did not know either.

What happened here? The left hemisphere could not see the left visual field, so when the stimulus appeared there, it answered two scientists that it did not see anything.

However, the right hemisphere sees a stimulating image. Something he can't say. So he tried to direct the hand to draw the image to answer the questions of the two scientists it heard.

Here, Sperry and Gazzaniga have a clear conclusion: A patient with 'brain separation' should be considered as two patients with half a brain. Sperry argues that this is beyond an answer to a question. It has proven materialism in the field of consciousness. If we divide one person into two when 'separating' his brain, there is no place for a soul of idealism to exist anymore.

Describe experiments with people with "brain separation".

So the question has been answered? Not really. We have to admit that patients with "brain separation" still feel the world around them and behave normally. If a 'brain-splitting' patient enters the room right now, you won't notice anything unusual in them.

These patients themselves also claim that no other person is separated inside him, except for the uncomfortable seizures that have disappeared. So if science says these people have been divided into two halves, something is not right.

To clarify the problem, a research team at the University of Amsterdam looked for two 'brain-splitting' patients and invited them to participate in an experiment. The purpose of this experiment is to assess whether they can respond accurately to objects in the left visual field (acquired by the right brain), while also responding verbally or with the right hand. (controlled by the left brain) or not.

Surprising results in these two patients, the team observed a completely different phenomenon than Sperry and Gazzaniga. Both patients exhibited full awareness of the presence and location of stimuli across the entire visual field - right and left.

When stimulation appears in the visual field on the left, they almost never say (or describe by hand) that they don't see anything. Instead, the two patients all pointed out exactly what position was there and where they were.

Even so, the two patients 'brain splitting' in the University of Amsterdam study were not entirely normal. They cannot compare the stimuli in the middle of the visual field.

Moreover, when a stimulus appears in the left visual field, the patient recounts the properties of the image better (both verbally and with right hand gestures). When a stimulus appears in the right visual field, the patient guesses its position better (with both words and left hand gestures).

How does a brain, consisting of many modules, create only one human?

Based on these findings, scientists have proposed a new model of brain division syndrome. When you separate the brain, you will still have only one person inside you. However, this person experiences two lines of visual information, for each school looking left and right.

Patients with 'brain splitting' cannot integrate both fields together. It is like when you see an error movie, in which the sound and picture do not match.

And finally, while the previous experiment of Sperry and Gazzaniga showed strong evidence supporting materialism (that when we split the brain, the inner person will also be halved), the new results is supporting the mystery of consciousness.

When you divide the brain into two halves, you still have only one person. How does a brain, consisting of many modules, create only one human? And how are the parts of the brain synchronized when they are cut off from the path of communication? All is still a mystery to be discovered.
