Thomas Bayes and the Bayesian brain

Learn about Thomas Bayes and the Bayesian brain for you to discover Why can't you think about your own death.

The data on Thomas Bayes is scarce, just as the scholars of his work have highlighted, however, Bayes' discoveries have remained indelible despite the passage of time.

Thomas Bayes was a British mathematician, who also served as a reverend in a Presbyterian church.

However, Bayes' work that has received more recognition has been that of subjective probability, which, in addition, has had notable influence in other fields, such as law, economics and other sciences.

What is Thomas Bayes research about?

Thomas Bayes makes an approximation to the reality in which the probabilities are the central axis that allow us to know the world.

According to your perspective, human beings are in a constant integration of mathematical and statistical information, although many express that they do not feel love for mathematics.

But, the truth is that our brain always resorts to them, and not only when it comes to receiving a change after a purchase.

On the contrary, the brain makes constant use of mathematics, especially when it comes to making calculations based on probabilities.

This ability that our brain possesses is so strong that some studies have concluded that the calculation of probabilities is what guides most of our behaviors every day.

Mathematics is not only a subject in school, but we turn to them every time we make decisions or to perform simpler tasks.

How does the Bayesian brain work?

According to this theory, our brain allows us to understand how the world works, and this involves the different scenarios in which we can find ourselves immersed.

All this work apparently takes place in the orbifrontal cortex. So that, We do not perceive the world as it really is, but as our brain supposes.

This work is sharpened with the help of the sensory impulses we receive from the external world.

The importance of Thomas Bayes and the Bayesian brain theory is that - according to inquiries about it - Our brain is guided by the theory of probability, or Bayes rule.

How far is our brain?

Our brain is an organ so powerful that no one can take the lead making predictions.

Indeed, it is often said that, before anything happens, our brain is already able to predict it.

Previously it was believed that our brain only received signals from our senses, but the truth is that this wonderful organ has an amazing predictive ability.

Only this is nothing new, Thomas Bayes' mind had already predicted it in the 1700s.

This author considered that our brain made prediction processes and updated their beliefs.

This would explain why seeing a dog the brain is able to predict that the animal will attack, and this belief is updated and increases fear if we get to observe that it is a doberman without a muzzle.

But what happens when we think of our own death? In a recent study, scientists gathered several people and proceeded to keep the records to reach a conclusion.

Study on the response of our brain to death

The brain of the people involved in the research goes out, or at least his predictive ability - to see his own photographs next to the word "death," or "burial."

The amazing thing about this study led by Yair Dor-Ziderma is that We not only make predictions of what happens outside, but also of our inner world.

After seeing several things - images, objects, situations - repeatedly, the brain can predict what will happen.

But, seeing something different, then it will show a high wave, that is, it will be surprised, and this is called "prediction error."

When this happens, the brain updates the model it has about the world and, just as we have beliefs about simple things, it also happens with respect to death, only we don't relate it to ourselves.

What happens in the brain and death?

Following the theory of the Bayesian brain, when the brain sees itself related to death, something indicates that the information is unreliable.

The human being fears death, we are all afraid of this inescapable fact, and it is completely normal.

That is why humanity has created myths to try to explain what would happen after death.

Don't you think all these scientific conclusions are amazing?

Can you imagine that our programming would have been to live forever?

If so, then we would understand why Our brain "shuts down" at the idea of ​​dying.
