The way the brain deceives the body without knowing it

The human body is a unified mass of countless complex components . The brain, senses and parts of the body work in concert to reflect and help people respond appropriately to the situation in the outside world.

However, this system is also not perfect. Sometimes, the system also has an error and then you will feel like being "fooled" by your body .

1. Hallucinations

A cognitive neuroscience researcher from the University of Geneva, Alexandre Pouget said: 'The human brain continuously creates predictions about the world around and reflects back to the sensory system. That's why you recognize and interpret the objective world according to your predictions. '

We can take an example like this: if you are walking around the block and see a person approaching you. The brain will immediately start calculating the ability and guess what that person is like.

That's why many people will think this person is a neighbor instead of a distant friend. In most similar cases, you will predict correctly.

According to Pouget, many people believe, we will look at a face to find the identity of a person, but in fact the brain has predicted this logically.

The prediction of the brain also affects people when we apply it in optical illusion. Pay attention to the picture on the picture.

Due to the length and narrowing of the black lines, we often think of train tracks. With this prediction, humans will automatically assume that the yellow line is at the end of the road longer than the front line. But the truth is, these two straight lines are completely equal.

2. Fake memories

We often think of memories as actual tapes that record memories. But some studies suggest that each time we recall a memory, they may have been deformed.

Oliver Hardt, a researcher at the Center for Cognitive and Neurological Systems at Edinburgh University, said: 'When you recall a memory, it is likely that it has been deformed, become false.

Because any element of your surroundings at the time of storytelling can affect the authenticity of that memory. '

A testament to this is the fact that countless people had to go to unjust prison after being identified by witnesses. The results of DNA testing indicate that those people are really clean.

3. Music syndrome in the ear

Neil Bauman, director of the hearing aid center, has recorded more than 1,500 cases of 'in-ear' syndrome. The patient will hear songs that only appear in their heads and no one else hears.

He explained that this phenomenon was due to the sound of the patient's memories in some way spawning in their heads. The brain receives this signal and by default the sound is real, heard by the ear.

Many psychologists often do not recognize this syndrome. Many people laughed and said that their patients simply had problems so write them a prescription for mental health treatment.

In fact, patients need to be treated more sensitively. Stigma needs to be removed to understand more about this strange syndrome.

4. Charles Bonnet hallucination syndrome

This syndrome can be considered a visual version of music syndrome in the ear and often occurs in the early stages of vision loss.

Accordingly, patients will often 'see' things that are not available, such as a farm image showing up on a wall or ghostly hovering .

Like the music syndrome in the ear, Charles Bonnet hallucination syndrome can be very scary for many people because they easily think that they are mentally ill.

However, the researchers suggest that this phenomenon is simply that the brain is filling the void of loss of vision with images stored in the brain.

5. False limb pain

This phenomenon usually occurs in people who have lost their limbs due to accidents or patients with spinal cord injuries. It is also called 'ghost' pain. At that time, patients often feel pain in areas of the arms or legs that have in fact gone.

This pain was previously assumed to be a psychological problem. But experts today blame the spinal cord and brain.

The nerves previously used to transmit signals from the limbs to the brain now cause pain. The pain is often different depending on the condition of each patient.
