Brains might not use natural language for logical reasoning. Or they don’t use language. That we can use in a verbal form. This means that the brain’s internal communication requires a different communication protocol. Than humans use in communication with other people. We can call those protocols languages. But logic doesn’t need a similar language. As we use in speech. Logic needs communication. And a way of communication. It can be different. But we can call that communication “language”.
We understand natural languages as language. That we speak and write. But nature is full of languages that we cannot use in verbal communication. Things like hormonal and pheromone-based chemical communication. It's very common. Most of the neuron’s mutual communication is a combination of electric and chemical signals. So that means those communications. They are also natural. But the key component in information is this. Brains must have an ability to separate external and internal signals.
Brains are very complicated structures. They contain many hidden neural networks and hidden layers. We know that only a small part of the brain's internal communication reaches consciousness.
This raises an idea. That maybe humans use different languages to communicate with other people. Than brains use their internal communication. So could the cerebral cortex. The diencephalon and brainstem use different communication languages for internal communication.
If the brainstem uses the same language for internal communication as the cerebral cortex. That could disturb the brainstem's internal communication. And that can cause death. The brainstem controls vital functions like blood pressure, pulse, and other things. In some models. The diencephalon has a mission. It is to translate brain signals from the cerebral cortex. To the brainstem. If those three brain layers use the same language. That can be hard. To separate the signals. And that can cause problems.
When we expand this model. We can say that maybe all brain areas, including the cerebellum, have different languages. The cerebrum and cerebellum have different languages. But brain lobes like the frontal lobes and temporal lobes. They use different types of dialects. That helps the brain separate signals. That come from a certain area. And that helps to keep those signals in order. This is important. When. Brains make decisions. About the reactions to a certain stimulus. Every stimulus requires a different type of response.
So. The use. Of different languages. In internal and external communication protects brains.
It’s possible that all human brain areas use different types of language. If we want to use computing as a model. How the brain analyzes information, we must take note of. Computers have three types of programming code. The lower-level programming code. That code connects the hardware to software. The operating system level. And the highest part is the program. All three main layers are made using different types. Of programming language.
Those three layers are meant for internal computer communication. The network communication uses other protocols and languages. Than the computer internal data flow. But then we can transform that model to the human brain. If human brains use different languages than humans use in communication with other people. That protects the brain from outside effects. In this model, information comes to the brain. through the brain area. That is reserved for a certain sense. When other humans speak. Data travels in the brain lobe.
That handles those types of signals. Information travels to the Broca lobe. There, those neurons translate that signal into the form. That. The brain understands it. If humans. Use the same language for internal and external communication. That thing causes a situation. That other person can take another person under control. Because external communication is different. Than the brain's internal communication. Brains realize. That data comes from external sources.
