I suggest you to plunge into the world of the greatest mysteries of the human brain that science has not yet found answers.





A cursory review of the state of modern science in the unsophisticated reader might get the impression of a strange inconsistency. The size of the object of research surprisingly does not reflect the progress made in its study. For example, the science of the brain - the organ, weighing an average of 1, 5 kg, require such sophisticated technology, but until now it has not disclosed its many secrets. How so? What's the mystery keeps the human brain, why scientists are forced to wrestle with deciphering how it works?

Nature or nurture?

One of the main aspirations of Sciences, studying the brain and psyche - is to determine the degree of influence of heredity on the development of personality in comparison to the impact of external factors, such as education, environment, friends, idols and so on. What determines the character development, the future of addiction and desire? A study of twins as individuals with the same raw data into heredity, can give a significant clue, because they represent an ideal object of study the difference of congenital and acquired.
High hopes for the study of separated twins at an early age: the only way to know for find out what qualities siblings will develop and whether as similar as if they grew up together. However, in view of clear ethical reasons such aspirations are doomed to failure in full. Fragmentary data, accessible to researchers, show that twins who were separated at birth revealed similar down to the smallest detail of habit and addiction (eg, sucking the same finger or a preferred school subject), but in relation to other manifestations of nature, as we found out there was no such a pronounced similarity.



Why the brain stops functioning?

Unfortunately, sometimes people have to watch a sad picture of how the once flourishing body suddenly ceased to perform its core functions and all clearly established system seemed to begin to disintegrate. The brain is no exception and is just as likely to lose its former performance up to a full stop work. The most famous example of such a sharp Degeneration - Alzheimer's disease. Even despite the fact that scientists have found a specific place in the brain that affects a disease, stop already running mechanism of destruction they are not yet in force. Medicine does not have at the present time means capable of preventing the development of fatal process ... Unfortunately, as soon as science knows the structure and functioning of certain parts of the brain, an integrated organization of its work, and in particular, disorganization, are still more than mysterious. < br />


Secrets of sleep and dreams

It is quite natural and familiar that people have dreams, but as this is not surprising, scientists still do not know why this is happening. The only thing they have taken to assert with confidence - it's unconditional importance of sleep for the body.

In an attempt to push the assumptions about the purpose of sleep is leading theory needed rest and relaxation provided by the brain at this time. However, when it comes to vacation, why the brain itself is more than active, producing a dream? Perhaps in a dream comes training necessary reactions, study of emotionally significant events and solving urgent problems for a better response then waking.



Unraveling the memory traces

Another mystery of the brain is incomprehensible until the memory device. What mechanism is responsible for to keep certain facts and events, and how to determine the extent to which they need to?

Scientists have established brain areas, pockets of neurons and their connections, responsible for fixing anything in memory. But that's what happens in these fields is still unclear. Even less is known, whether intentional change in the structure of memory mechanisms in order to delete a specific part of it.

One study showed that the activation of neural connections when recalling events is almost identical to the reaction of nerve cells in the perception of the same in the past. Thus, we can assume that the experience of phenomena in reality and in the memories make the brain function quite similarly.

In addition to the study of memory function in the state standards, very interested in the topic of her violations, such as false memories. In 2005, when in London a series of explosions, doctors and the police witnessed 10 different stories about people allegedly seen them on TV frames relating to the incident. However, no such videos on any channel has not been demonstrated.

What is the purpose of memory, if it retains a sometimes unreliable data?



The riddle of consciousness

Until now, science is not clear - the brain where it ends and begins the mind. Maybe it's the same thing? What about concepts such as soul, individuality, personality? That this holds the brain and in what proportions? This area is the study of the human mind as the most fundamental and the most subjective.

Thanks to modern imaging techniques, scientists can record the activity of certain brain areas during certain actions. But how to understand - how and when this activity becomes a thought?

Also remains unclear sphere of conscious and unconscious experience. Many processes do not require the involvement of a conscious understanding of: breathing, stomach, gait and more. Furthermore, there are unconscious activities and higher levels, for example, 7 seconds has to decide a person can observe a lesion in his brain, signaling behavior model is completely formed. Does such event, the freedom of the will, or all our behavior - the result of mechanical work of a complex system of nerve cells?
