10 Human Brain Mysteries unsolved

10 Human Brain Mysteries unsolved


Never mind the environment, we ourselves still many question marks. The human brain can be likened to a computer processor. The difference is, processor performance can be described in logic, while our brains are not.

There are ten mystery that still envelops the ins and outs of the human brain. Scientists are still trying to find a scientific explanation. But still the mystery of God's creation is the secret of life exceptional. Here are 10 mysteries surrounding the human brain that we experience daily, but still we are unable to find the cause.

1. Awareness

When we wake in the morning, we woke up from sleep. Enjoy the sunshine from the slit windows, nan cool morning air, and so on. We call it consciousness. This field trigger multiple topics discussed scientists since ancient times. Advanced neurology experts describe consciousness as a realistic research topic.

2. Frozen Life

Eternal life is only present in the human imagination. But scientists have found cryonic, findings which could make the human being has two lives. Cryonic center is one of the Alcor Life Extension Foundation in Arizona, which stores the living body in a tube containing a liquid nitrogen temperature of 320 Fahrenheit minud.

The idea is that people who have died from the disease will be thawed and revived in the future when the disease was curable. the body of Ted Williams, the famous baseball player are stored here. Since the technology has not been found, the revival has not been performed. but his body had been "melted" by an appropriate temperature so that the cells freeze and break.

3. Mystery deaths

How do humans get old? humans are born with the body's mechanism that is able to withstand the disease. That's why the wounds can heal itself Wanta treated. But along with increased age, the mechanism is reduced. why is that? There are two theoretical explanations. First, aging is part of human genetics. Kedia, aging is the result of the body's cells are damaged.

4. VS Natural Care

The debate about the human mind and personality are still struggling between the two things above. Personality and human thought is said to be controlled by genes or environment? Or it could be both? There is still no consensus among scientists about this.

5. Triggers Brain

6. Memory

Some unforgettable experience, rather we just often forget important things. How could that happen? using brain imaging techniques, scientists have discovered a mechanism that is responsible for the creation and storage of memory. they found the hippocampus and gray matter of the brain that acts as a memory box. But why is there a memory that is memorable and dipukana, still remain a mystery.

7. Biological clock

Suprachiasmatic nucleus of the brain also has a biological clock nucleus alias. This section is programmed to follow the rhythm of the body within 24 hours. Biological Clock also adjust the body temperature, sleep wake cycles, as well as production of the hormone melatonin. Last debate is whether melatonin supplements can prevent jet lag?

8. Haunted by feelings

9. Sleep

Why do humans need sleep? Scientists know that all mammals need sleep enough. Not getting enough sleep will cause prolonged halunisasi even death. There are two levels of sleep, namely sleep, non-rapid eye movement (NREM), occurs during brain showed low metabolic activity. Then levels of rapid eye movement sleep (REM), when the brain is still quite active.

10. Dream

Apart from sleep, the dream is also a mystery. Chances are, dreaming is an exercise that stimulates the brain synap traffic between brain cells. Another theory says humans dream about tasks and emotions that could not be considered as long as they awake in the daytime.
