Developing individual intellectual ability, you must take into account the impact of various factors that influence the physiological state of the brain. It is believed that for the successful development of their abilities by training the brain chemical necessary three conditions:
1. A well-balanced nutrition for normal neurons;
2. The relative freedom from stimulants (nicotine, alcohol, caffeine) and other drugs, as any substance that can significantly change the emotional state, in fact, destroy the brain;
3. To prevent entry of toxic substances into the brain, including many food additives.
This is a very narrow list. The brain works at full capacity and prevent cardiovascular and hormonal disorders, stress, lack of sleep, injuries and diseases of the head and spine, the effect of various stimulants (caffeine, nicotine, alcohol, etc.), Multiple food additives and household chemicals, and other factors. Let us briefly consider a few of them.
The brain — is not only a center of intellectual abilities, but "conductor" the entire hormonal system. Synchronize the work of hormonal system corresponds to a sharp mind and good health. Melatonin protects not only interneuronal communication, but also the cell nucleus that contains the DNA. Decreasing the amount of melatonin in the brain tissue is one of the causes of Alzheimer’s disease. Sex hormones activate the brain and spinal cord. For example, adrenaline improves memory. Therefore it is better to remember the event, accompanied by strong emotions. Elevated levels of testosterone in men is able to improve memory and spatial reasoning, and the lower the concentration of testosterone, the higher their linguistic, artistic and creative abilities. Testosterone also activates the memory mediators such as acetyl choline. Deficiency or lack of estrogen leads to the death of neurons which produce dopamine, which is involved in the transmission of signals between neurons. In adulthood, most of our adrenal glands produce hormones. Adrenal lead to depletion of alcohol and smoking and diet high in refined carbohydrates and sugar, chronic stress and environmental toxins. People who have survived to a ripe old age mental clarity, by nature have a high level of growth hormone — somatotropi-on. In order to balance the level of catfish totropina important enough sleep, active physical exercise, consumption of sufficient amounts of protein foods, limit sugar and carbohydrates receive high glycemic index. Serotonin, a hormone good mood, also activates the brain, increases talkativeness. Too low level of serotonin in the brain leads to depression. Thyroid hormones are necessary for memory and mind. In hypothyroidism (deficiency of these hormones) is slowing down biochemical processes in the gray matter of the brain. Cells deficient in oxygen and nutrients, reduces the number of interneuronal connections. Endogenous Opio-dy (endorphins and enkephalins) have a marked effect on learning and memory, slow down the extinction of conditioned reflexes, improve their preservation, though impair their formation.
Under stress, sometimes called "silent killer"Usually suffer all aspects of intellectual activity, including such basic properties of intelligence as memory and attention. Violation of the indicators of attention in the first place due to the fact that in the cerebral cortex of man a so-called "Stresa-dominant weed"Around which are formed and all the thoughts and feelings. In this case, complicated concentration of any attention at other sites, and there is an increased distractibility. Memory function under stress suffer less. At the same time the constant workload stressful problem of consciousness and the search for solutions it reduces the capacity of the memory, and the changes in stress hormones makes irregularities in the process of extracting from the depths of memory required information. It was found that the quiet man is able to remember and recall two times more information than a person in a state of stress. When stress is eliminated and adequate alternative thinking, so at least one half of the brain is blocked or access it through the corpus callosum that connects the hemispheres of the brain, it is not possible. Even a small stress prevents the emergence of new neurons. Constant stress destroys not only neurons, but acts on the blood vessels of the brain, leads to sclerosis and, hence, to an increase in risk and cerebral infarction and heart. Stress interferes with the activities of the dendrites. By eliminating the situation causing the stress, their functions are restored, but not completely — about a third of the damaged dendrites will be lost forever if later stressful situation arises again. When chronic stress and depression, Hippo Camp and frontal cortex ("Zone complex thinking") Depleted.
Depression is accompanied by a dysfunction in emotional and cognitive centers of the brain, there are specific changes in the DNA in the brain. Depression reduces brain activity and can lead to conditions reminiscent of dementia. The risk of de-dementia triples. If untreated depression actually doubles the risk of Alzheimer’s disease.
Sleep can be put on the first place among the factors of health of the brain. Sleep not only slows "erasure" information, but also contributes to the transfer of information in long-term memory. Get enough sleep is a prerequisite for a good memory. One of the causes of acute brain function during sleep is to consolidate the information received. In the course of this work in neural cell protein synthesis occurs. Therefore, prolonged sleep is important to nerve cells would be enough time for protein synthesis. If disintegrating proteins in nerve cells are not replaced by other, the information stored in the memory will gradually fade. Sleep deprivation is particularly strong effect on the mathematical abilities. Deprivation of even a small amount of sleep a night — 6 hours instead of 8 a few nights in a row — can cause a marked increase in the reaction time and the deterioration of the results of standard tests for mental activity. Deficit sleep is also associated with depression and attention deficit disorder. In addition, lack of sleep causes an increase in the level of the stress hormone cortisol in the brain, which can also cause memory impairment. It was found that people who sleep less than 7 hours a day, reducing the overall blood flow to the brain, which is also a negative impact on their intellectual abilities. Dream of protecting a cell of the cerebral cortex of the depletion and destruction. During sleep restores the energy of nervous tissue. It should be noted that during sleep the brain is more active than when watching TV.
Excessive TV reduces attention and a few breaks memory adversely affects the ability to perceive and organize information. It was found that adults who watch TV two or more hours per day have a significantly greater risk of developing Alzheimer’s disease. Finding a person more than an hour a day at the TV screen, computer or mobile phone use, reduces 1.5 times the ability to remember new information that is related to the influence of electromagnetic radiation on the brain. Low-frequency electromagnetic field can selectively inhibit or enhance the biological rhythms of the brain. Particularly exposed to electromagnetic fields of the hypothalamus, a hybrid of the endocrine and nervous system, often called "brain brain". It is more than 100 times more sensitive to magnetic fields than the brain and all other tissues of the body.
Known statement of the Swedish neurosurgeon Professor Leyfa Sal-ford: "The voluntary exposure of the brain to microwaves from a mobile phone — it is the largest biological experiment on man". Mobile phones are currently the most intense emitters of electromagnetic waves. They concede, even computers and microwave ovens. The area of exposure during mobile phone — especially the brain and peripheral receptors vestibular (inner ear responsible for our coordination in space and normal tolerance of various transport), the visual analyzer. Repeated exposure of the electromagnetic field of the mobile phone area of the pituitary gland causes a decrease in the activity of the pituitary gland — the reduction or complete cessation of production of regulating hormones. When using a cell phone for more than 10 years destroyed brain blood-brain barrier, it is physically and chemically protect the brain against the penetration of hormones, bacteria and proteins in brain tissue. The electromagnetic field leads to increased permeability of cerebral blood vessels, their brittleness, which increases the risk of heart attack and brain stroke. Furthermore, the risk of occurrence of a benign tumor of the auditory nerve. Worsening memory, increased blood pressure, insomnia occurs and premature aging. With a constant and prolonged use of mobile phones, lost resistance to stress, and may eventually develop Alzheimer’s disease or Parkinson’s. Under the influence of the electromagnetic field in the tissue itself and its cells to change the activity of certain enzymes action. The result is a compound such as nitric oxide. Nitric oxide has a toxic effect on the tissue of the brain and the whole body. Accumulating, it impairs blood flow in the brain, and the brain is experiencing oxygen starvation. Moreover, direct affects toxic effect on the neurons included in the gray and white matter of the brain. When talking on a cell phone in an adult exposed to radiation of 20-30% of the surface of the brain.
German microbiologist Robert Koch believed that the noise for people just as dangerous as the plague or cholera. Auditory areas of the brain are so-called zones "rough" processing. How well is the information received by the auditory organs of hearing and auditory areas of the brain, so it will be processed qualitatively area of complex thinking. The impact of noise on the central nervous system leads to disruption of brain activity to the manifestation of common functional changes in the body (with the noise of 50-60 dB), significantly alters brain potentials, causes biochemical changes in brain structures. Early hearing loss contribute to the same factors that cause atherosclerosis — a sedentary lifestyle, fatty foods, smoking. Prolonged exposure to the organ of hearing loud music (4-5 hours) through earphones MP-H player or at the disco causes thickening and swelling in the nerve fibers that connect the cochlea of the inner ear to the brain. For their healing requires about two days. When the daily noise load ears not created the conditions for the regeneration of the cells, there is hearing loss, and the right ear, as a more informative, the first to suffer. Especially harmful listening to music through headphones in transport, as there is a superposition of different noises, which greatly weakens the auditory nerve.
Particularly serious consequences for the intelligence have head injuries. Injuries often result not only in loss of memory, but also to the development of Alzheimer’s disease. About 60% of people received minor injuries, even after three months after the incident, still suffering from memory impairment. Shock trauma cause vortex motion around the brain ruptures of nerve tissue, and extensive damage to a large area of blood vessels. A strong impact can cause the formation of a blood clot in the brain, as well as head and microtraumas may cause the formation of numerous small blood clots in the brain. Perhaps a brain hemorrhage, resulting in swelling and tumors appear, blocking the supply of oxygen to the brain. Even non-severe traumatic brain injury can eventually cause encephalopathy, hypertension, accelerate the formation of atherosclerosis and lead to a breakdown of the brain’s ability to regulate the condition of many organs, perform their various functions. Very often, after the head injury varies intracranial pressure, often — in the direction of its increase. Most of these disorders develop in the first two years, even after mild concussion. Research scientists patients had recently received a slight concussion showed that their brain works just like being in a coma for people with severe head injuries. So, even if the patient can walk, talk, and apparently seems normal, it does not mean that his brain is fully functioning. Moderate brain injury lead to drastic changes in the metabolism of the brain and can make it more susceptible to injury during the second strongest impact. For example, the force of impact with the player receiving the ball on the head of up to 200 kg. For football season gets about 1,000 strong blows on the head with the ball. As a result, strikes his head on the ball, damaged front end of the temporal lobes, which can affect memory, language abilities, and emotional control.
It is known that the brain is an extension of the spinal cord. It was established that in diseases of the spine lost 1.3 cm3 of the brain in their respective fields. This is equivalent to aging for 10 or 20 years. Hence the need to maintain the spine in a healthy condition, the use of different methods of unloading the spine, for example, swimming on his back, stretching exercises.
Acceptance of any stimulants destroys brain! For example, if we take a blood alcohol concentration of 100%, in the stomach it is 20% -80 intestine, liver — 148, in the cerebrospinal fluid — 150, in the brain -175%. Under the influence of alcohol decreases the permeability of the capillaries of the cerebral cortex, which means — it is getting worse food. Particularly reduced blood flow to the frontal brain pain, where there are areas of complex thinking, speech. First of all after drinking alcohol disrupted the activities of the cerebral cortex, and then — the basal ganglia, spinal cord, and in the last instance — the vital centers of the medulla oblongata. Alcohol directly affects the cerebellum.
Alcohol and smoking are not compatible! Alcohol has the properties of a universal solvent. Under its influence the toxic substances contained in tobacco (more than four hundred thousand), are retained in the brain cells is much longer than that is laid, breaking the course of biochemical processes and slowing down the thinking. When smoking, due to spasm of blood vessels of head, there is a profound cooling cortex of the left hemisphere of the brain, especially in the neck. Smoking leads to the weakening of hearing, sight, smell and taste, which leads to poor quality "rough" Information Processing projection areas of the brain. Even after one smoked cigarette for reduction of oxygen in the blood to normal levels is necessary for at least 8 hours. Caffeine and nicotine — strongest vasoconstrictors, reducing blood flow to the brain, and in particular to its temporal lobes. Caffeine blocks the production of melatonin in the brain. Caffeine dramatically reduces the amount of vitamins "AT" and increases the stress hormone. B vitamins "AT" are essential for normal brain function. They enhance the activity of the brain controlling processing of information, and are used to remove toxic waste byproducts of cellular metabolism. Frequent consumption of foods with a lot of caffeine hinders concentration and leads to frustration memory. Caffeine has an effect similar to the effect of the stress hormone — cortisol, which is produced by the adrenal glands. The brain for a short time comes to an excited state. Caffeine also increases the effects of alcohol on the brain.
No less dangerous for the brain are supplements, various household products and pharmaceuticals. Of all the organs of the human brain is the most sensitive to poor-quality food. For example, a food additive, aspartame (E951), which is 180 times sweeter than natural sugar, can cause memory loss, lethargy and sleepiness, epileptic convulsions, severe speech disorders, tremor strong, strong hyperactivity and restless leg syndrome, facial pain. Aspartame damages neurons of the brain due to their excessive stimulation. While aspartame does not completely absorbed, it produces in the intestine formaldehyde (formic aldehyde, methanol) and methyl alcohol (methanol, or wood alcohol) which cause lesions of the optic nerve that can cause blindness. Additionally, aspartame can cause the formation of tumors in the brain. Neurotoxic effects of exposure to formaldehyde and methyl alcohol on the body accumulate! Lesions of the brain cells and the optic nerve methanol and formaldehyde are irreversible. Another food additive, monosodium glutamate, a flavored supplement that our brain is not completely necessary. It is so burn through brain neurons, some of them die from excessive depletion. It destroys the myelin layer and neyrotransmit-Thera (chemical transmitter of signals between neurons). Glutamate is responsible for the development of the process of destruction of neurons in a number of neurological diseases: Alzheimer’s disease, traumatic brain and spinal cord, multiple sclerosis, etc. It stimulates the progress of these diseases.
The volatile substances contained in many common household products (solvents, nail polish remover, hair spray, aerosol and so forth.), A devastating effect on the cortex of the brain, causing impaired memory, inability to digest the information, the changing nature, hallucinations and even death. These substances damage the brain, killing neurons by destroying the protective myelin surrounding the nerve sheath, without which no work interneuronal communications. Causing damage to the cells of the vestibular apparatus, many volatile substances cause temporary or permanent loss of coordination, slowing of speech, stiffness, tremor, and symptoms resembling Parkinson’s disease.
To be smart, you have to be healthy! Severe colds, flu, indigestion, high blood pressure and lead to the emergence of temporary memory problems. It also may include conditions such as high or low blood pressure, diabetes, and various brain tumors, thyroid problems, hearing loss and vision, vitamin deficiency, especially caused by alcoholism. Allergies slow thought processes and create difficulties in working memory and intelligence, reduce the time of possible focus. Scientists say that there is a link between the poor condition of the teeth and the deterioration of cognitive function of the brain. A significant loss of teeth increases the risk of disorders of the brain more than three times. Gum disease can affect brain function in various ways, for example, causing an inflammatory reaction. To reduce the intellectual potential cause hypothermia and head. This reduces the overall efficiency of the brain, there is Vega-tososudistaya dystonia, spasms of cerebral vessels. Scientific studies have shown that low temperatures act on the brain like poison, causing massive loss of neurons, particularly in the hippocampus, is also responsible for working memory.
Many commonly used drugs today, including reducing acidity, painkillers do not contain aspirin and cholesterol-lowering, can lead to a deterioration in the supply of the brain essential nutrients needed to maintain its optimum level of functioning and prevent aging. The negative impact on memory has a number of antidepressants, antipsychotics, antibiotics, anti-diabetic and protivoast-matic agents and anti-convulsive drugs. Impairs the brain food preparations containing estrogen. Hypnotics and heart medications are most dangerous for the memory. Adversely affect the operation of memory, and many fat burners, and even some antibiotics. Temporary memory loss can cause medications: stimulants (containing imipramine, amitriptyline, dezipra-min, nortriptyline, etc.), soothing (on the basis of lorazepam, oxazepam, alprazolam, hlorazepama, triflyuo-perazima, tsioridazina, hlorpromazi-on, chlordiazepoxide diazepam) and other medicines (anti-motion sickness, pain, antiallergen, anti-inflammatory, containing propranolon, skopolimin).
