Brain located in the skull that are directly related to the spinal cord , as well as forming a central nervous system . Compared to whole body weight , brain weight was only 2-3 per cent .However , the brain is very big role in everyday life . Although it weighs very little , but their need for oxygen and glucose compared to most other organs .
In adults , required 600 milliliters of oxygen ( 25 per cent of the total oxygen consumption by the body ) and 100 milliliters of glucose per minute . As much as it needs to be carried by one liter of blood ( 20 percent of all the blood that issued the heart each minute ) flowing to the brain .Cessation of blood flow for three minutes can lead to brain cell damage , whereas blood flow stops for more than nine minutes would result in death .
The composition of the brain is very complicated , but it can simply be divided into two groups , namely a large brain ( cerebrum ) and the brain (cerebellum ) . Big brain is 70 percent of the entire brain , and is responsible for the level of intelligence and ability to think we are .
In this big brain , the information received by the sensing organs processed , concluded and addressed . Small brain volume of about 10 percent of the entire brain , functioning as a controller coordination and balance .
The level of intelligenceIntelligence is a mental ability that is carried by an individual from birth to adjust to the new environment and solve problems quickly and accurately .
The level of intelligence of the child is determined by the state of the brain and are influenced by many factors , such as the nature of genetic , environmental ( facilities , family socioeconomic ) , motivation , and nutritional status . Versatility person can be measured by means of electro- encephalogram ( EEG ) , positron emission tomography tool ( PET ) , and IQ tests .EEG can capture and record the current wave emitted by the brain . While a record of PET brain reaction to a problem . Brains need less reaction to solve the problem . While the less intelligent seem to exert almost all the parts of his brain to answer the same problem .
IQ tests have been used for a long time . This test as a way to predict a person's level of intelligence . Famous people shown to have a high IQ .
For example , Albert Einstein was very expert in the fields of physics , mathematics , and also a very skilled violinist that has an IQ of 172 ( 72 percent higher than the average person ) .Similarly, Henri Poincare , a mathematician known for the sharpness of his intuition was noted to have an IQ above 200 . Plato, Michael Angelo , Mozart , and other figures of history have recorded as the owner of a high IQ as well as experts in their respective fields .
According Tirtonegoro (1984 ) , the level of intelligence of a person spreads normally ranging from the lowest to the highest , which is 1 percent of a severe disability / idiot ( IQ 0-25 ) , 2 percent rather severe disability / imbeciles ( IQ 25-50 ) , 20-25 percent disability light / debilitated ( IQ 50-75 ) and a slow learner ( IQ 75-85 ) , 50-55 percent rata-rata/normal ( IQ 90-110 ) , 20-25 percent superior ( IQ 110-125 ) , 2 percent very superior / gifted ( IQ 125-140 ) , and 1 percent of a genius ( IQ 140-200 ) .
The development of the human brain started since he was a fetus in the womb . Therefore , pregnant women are required to always create a good nutritional status and adequate care for the baby that would be born to experience optimal growth process .
lack of energyMaternal nutritional status is closely related to weight baby to be born . Pregnant women are one group of people who are particularly vulnerable to nutritional problems , especially the problem of shortage of energy and protein ( PEM ) . Babies born to mothers with the condition of the PEM will have low birth weight ( LBW ) , which is less than 2.5 kg .
LBW conditions will greatly influence the subsequent development of the child's health . In addition to malnutrition , newborn babies will also decline brain development . This will result in a decrease in learning ability and academic skills at a more advanced age . In addition , the possibility of LBW infants have died before the age of one year , 17 times greater than children who are born with normal weight .
Pregnant mothers are well nourished will have the weight of an average of 12.5 kg during the 9 months of pregnancy and will give birth to infants with an average weight of 3.3 kg . To achieve these conditions , pregnant women should consume enough food ingredients source of energy, protein , vitamins , and minerals .
Average additional energy required during pregnancy is 80,000 kilocalories . The amount is divided into 150 kilocalories per day during the trimester ( three months ) first , and 350 kilocalories per day during the second and third trimester of pregnancy .
Additional proteins that are required to achieve the normal state is 925 grams , which is an average of 3.3 grams per day during pregnancy . Additional proteins that are required during the first trimester , second , and third respectively 1.2, 6.1 and 10.7 grams per day . In addition , it is also necessary vitamins and minerals that can be derived from vegetables and fruits .
PEM conditions in pregnant women , of course, will greatly affect the baby's brain anatomy that would be born , Taitu regarding brain weight , number of brain cells , and the cells of the brain . It is known that the anatomy of the brain correlates with the level of intelligence of children in the future .Another thing to note is the consumption of polyunsaturated fatty acid chain length ( PUFA ) . Belong to a group of PUFAs are fatty acids Omega - 3 and Omega - 6 fatty acids .
Omega - 3 fatty acids are commonly found in marine fish fats consist of fatty acids linolenic acid eikosapentanoat ( eicosapentanoic acid = EPA ) , and acid dokosaheksanoat ( docosahexanoic acid = DHA ) , each of which consists of 3,5 and 6 pieces ties duplicate . Omega - 6 fatty acids are commonly found in fat grains , consisting of linolenic acid and arachidonic acid .
Omega - 3 fatty acids , particularly DHA , have been known to very large role in brain development . That its presence is required in the person's brain growth period , ie since fetal life until the age of 2 years after birth .
In addition to oils derived from fish and marine fish , this time the food industry has made some additions to the DHA fatty acids in milk for pregnant women and infant formula .
