And then came the reality where this myth? There are several assumptions in this regard though nobo

Over the years the myth as we use only about 10% of the brain was widespread and the source promethazine of this myth has often been attributed erroneously to Albert Einstein. It seems, however, that each part of the brain is used, despite Hollywood movies and some that you could not believe it.
Leaving aside all the evidence we have on brain function, even we can intuitively realize that if 90% of the brain would be used for something, then damage to those parts of the brain that represent promethazine the 90 % does not affect anything a person. In reality, damage any part of the brain, promethazine even in a small way, will produce profound effects on a person suffering promethazine from this condition, promethazine at least in the short term. Moreover, given the energy of the body that is used by the brain, where 90% of it would be worthless, it would mean that in the body there is a waste of energy that is incredibly high. To highlight some concrete evidence promethazine on how the brain works real, brain scanning techniques promethazine such as positron emission tomography promethazine (PET Positron Emission promethazine Tomography) and technologies promethazine based on magnetic resonance imaging (fMRI Functional Magnetic Resonance Imaging) shows that during the sleep in every part of the brain may reveal the presence of brain activity and that most areas of the brain are active at a time, assuming that the person whose brain was scanned not ever suffered from a form of brain injury. An intense promethazine research activity has been devoted promethazine to mapping the brain in terms of understanding the functional role of each part of the brain and so far has not found that there is a brain region with no specific function, although this function is not yet understood Fully.
And then came the reality where this myth? There are several assumptions in this regard though nobody has a sure answer to this question. Perhaps the most popular source in this respect, being the most often cited, is the psychologist William James and Boris Sidis Harvard who issued their theory on the "energy reserves" in the late nineteenth and early twentieth century. "We use only a small part of our mental and physical resources". Sidis even put his theories into practice as it concerns his son, William Sidis, who was a child prodigy who for a time was considered the smartest man alive because promethazine his intelligence quotient IQ . However, even Boris Sidis rejected tests attempting to measure intelligence, considering them "stupid, absurd and highly misleading." Theory promethazine "energy reserve" promethazine was later summarized by Lowell Thomas as "a person average only 10% develop their latent mental capacity "and, of course, promethazine at some point evolved in popular culture as" Use only 10% of the brain ". Another theory states that this myth comes from a misinterpretation of a neurological research. For example, research from the early twentieth century indicate that only 10% of neurons in the brain are active at a time. Alternatively, other research indicates that only about 10% of the brain is composed of neurons, glial cells that support the rest and regulates the activity of neurons in various ways. Once the myth has become popular is easy to understand why people were attracted to such an idea. People are excited about this idea as it would naturally use only 10% of the potential promethazine power of their brain. Thus, if it could be released as if by magic, even just a small part of the remaining promethazine 90%, then one might be the next Albert Einstein or even could develop telekinetic and psychic powers as they Hollywood writers often imagine and others when the myth is brought into question. Even today there are many self-help books and seminars that are trying promethazine to help you unlock the mythical capacity of 90%. Finally it is better to use our time and money to try to further develop the "10%" we use already. More information: - The ability promethazine we have to see people's faces and to recognize them as coming from a particular part of the brain. People who have that part of their brain damaged, or its ability to cut in one way or another, often have difficulty recognizing people in front of them. Where extreme some people can not identify all the faces of acquaintances. This condition is called prosopagnosia
