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 bodies of living creatures in a tube containing liquid nitrogen with a 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. Because the technology has not been found, the revival has not been done. but his body had been “melted” with the right 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
Laughter is the least understood of human behaviors. The scientists found that during laughter, there are three parts of the brain involved. First, the part that thinks before we understand a joke. Secondly, the area that tell muscles to move for us to do something.Then an emotional area that inspires feelings of amusement.
John Morreall, a research scientist humor from the College of William and Mary, found that laughter is the response that do not play the story line with expectations. Laughter also can spread to others.
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
An estimated 80 percent of the sensation of experience include itching, depressed, comfortable and the pain came from the missing body parts. There are people who experienced their organs tidka visible but can feel. One explanation is the presence of nerve areas in one of the organs of the body that creates new konseksi the spinal cord and continues to send signals to the brain.
Why do humans need sleep? Scientists understand 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 the levels of rapid eye movement sleep (REM), when the brain is still quite active.
Besides sleep, dreams are 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 had not paid attention during their waking hours in daylight.
