BRAIN

Let's see what the features and structure were, what came out of the researches;

The most important part of the central nervous system. Its weight varies between 1000-1350 gr.

It uses 25% of all oxygen intake, 20% of calories and 15% of the blood circulating in the body.

The brain, which is 400 grams in the newborn child, reaches 800 grams at the end of a year and 1,200 grams in the fourth year.

By the age of five, more than 50% of the connections between neurons are established. So childhood is very important.

The connection capacity of neurons in one gram of the brain is greater than that of the telephone network all over the world.

Each neuron can reach the other neuron in less than 10 milliseconds. (This period is less than one-tenth of our blinking time.) - The activity regarding how long will be stored among the 1 billion to 100 billion bits of information sent to the brain via the nervous system every second is called memory.

-A mature person needs 250 ml of oxygen per minute while in a calm state. The brain needs 20% of this, that is, 50 ml of oxygen per minute. The brain tissue of 100 grams consumes 3.5 ml of oxygen per minute on average. Only the entire cortex requires 10 ml of oxygen per minute. The white matter remaining on the inner side is supplied with very little oxygen (1 ml / min). If the required oxygen does not arrive on time, unconsciousness and fainting begin to occur after 8–12 seconds. If the lack of oxygen lasts for 3–8 minutes (it differs according to the body), irreversible damage occurs in the brain. If the lack of oxygen increases to 8–12 minutes, brain death occurs.

- In order for oxygen to be delivered to the brain without interruption, the heart must carry 780 ml of blood per minute while in a calm state. In this respect, 15% of the heart's activity is allocated to the brain. Although the weight of the brain is only 2% of the body, the fact that it takes 15% of the blood indicates the importance of oxygen demand. The smoker's brain lacks 20-30% of this oxygen.

Brain cells die less and slower than other cells; no new cells are produced instead.

Human mind capacity depends not on the number of neurons (nerve cells) in his brain, but on the connections he establishes between neurons. All humans are born with around 15 billion nerve cells. The important thing is not how much this number is, but the connection we can establish between these neurons.

The more the brain is used, the stronger it becomes. With newly created connections, every part of the brain is equipped with a spider web. As it is used, wide highways are opened, which facilitates later journeys.

- Uses glucose and oxygen as fuel. If brain cells are deprived of glucose or oxygen, they cannot sustain the metabolic process that generates energy for their normal function. If glucose levels are low and the brain is not supplied with sufficient fuel, similar symptoms that occur in the absence of oxygen appear: confusion, fainting, unconsciousness, and death.

There are 4 main lobes in the brain

Cerebral Cortex: All human abilities such as mind, consciousness, language, thinking ability, reasoning and imagination arise from the cerebral cortex. When we look at the brain, the part we see is the cerebral cortex.
The cerebral cortex is divided into four sections called 'lobes';

1. The frontal lobe (front): Conscious thinking; In case of damage, there may be a change in mood and feeling. Located in the front of the brain, this lobe is associated with reasoning, motor skills, high-level cognitive abilities, and spoken language. In the posterior part of the frontal lobe, the motor cortex extends. This area of ​​the brain receives information from various lobes of the brain and uses this information to complete body movements.
2.Parietal lobe (side): It plays an important role in combining information from various sensory organs. In addition, some parts of the parietal lobe play a role in the use of objects and some spatial vision processing.
3. Occipital lobe (posterior head): It is the lobe in which information about vision is processed. Slight damage causes hallucinations.
4.Temporal lobe (temple): The perception of sound and smell, as well as the processing of complex stimuli such as faces and spaces, is provided by this lobe.

Cerebellum: It relates movement with the information coming from the sense organs. This lobe plays an especially important role in maintaining balance.

We will examine the frontal lobe.
The anterior frontal lobe (prefrontal cortex) is an important part of the brain for learning and attention. Attention, concentration, processing of information, reaction to action, relationships with emotions take place in this region.

Learning from experience and mistakes, problem solving, judgment, planning, and goal orientation are functions related to the frontal lobes.



The investment decision starts with the analysis of the information that enters your brain. True or false news, how do you interpret this news? How do you interpret this new information and reach a conclusion with the right or wrong experiences you have gained before, the emotions you experienced during that experience.

The prefrontal cortex collects, integrates, formulates, applies, controls, makes changes and judgments from all sources (including sensory systems). It decides the behavior that will be brought up as a result.

in prefrontal cortex disorders

• Inability to maintain attention, lack of attention.

• Easy distraction.

• Impulse control problems, hyperactivity.

• Inability to schedule time, delay.

• Lack of organization and planning

• Emotional dullness, schizophrenia, and mood disorders.

• Inappropriate urge and tendency to misunderstand.
can be seen.

Risk-return appeal
When the brains of gamblers are examined, it turns out that they have a weakness against risk and return. The reward introduced in gambling produces a situation similar to the activation of cocaine intake into the brain in cocaine addicts. (Hans Breiter)
It is observed that gamblers react less to the reward in the search for loss avoidance and reward. The severity of gambling disease is directly proportional to the decrease in activity in reward systems. As dopamine receptors become weaker, they are becoming less sensitive to daily innovations and changes. Another situation seen in gamblers is that they are not excited about losses or gains compared to those who do not. With desensitizing dopamine systems, gamblers try to comfort themselves with games of chance. Because as reward and risk increase, dopamine levels rise temporarily.
The dopamine that rises with winning provides an addictive pleasure. This emerges as giving less importance to losses than others in the following periods.
Prefrontal Cortex planning influenced reasoning. Gamblers underperform in restraint, time estimation, flexibility, reasoning. Impulse control appears to be weakened at the time of decision making. Here we come across the amygdala.

In gambling disease;
-Increase impulse control in the forehead cortex.
-Increasing the fear of loss in the amygdala.
It can be a cure for this disease. In addition, it is known that drug treatments are applied to reduce the dopamine rising during gambling.
While gambling disease occurs in this way, it is seen in similar situations in terms of investment. Short-termers who do not sell at 5% loss, but enjoy dopamine rising after winning at 3%. Or, considering their previous experiences, those who act with the wrong impulses saying that there is no need to sell at the stop, they can stretch the stopper a little more. They actually do the same thing as gambling. If the purpose of investment is to gain, he should set the rules in advance. If the cut-off point, where the profit taking point, or the dynamically exiting point is determined in advance, the brain does not experience stress.

AMIGDALA
Emotional memory and the region that has a role in the development of emotional reactions. It is part of the limbic system. The center of many emotions such as fear, anger, anger, pleasure, love, affection, aggression; It is the limbic system located in the middle part of the temporal lobe (temporal region) of the brain.

It would not be wrong to say that the amygdala is behind our impulsive behavior. When we are exposed to a danger, the emotional repertoire of the amygdala is triggered by the brain with primitive questions. Is this something I hate? Will this hurt me? Is this something I'm afraid of? as. If the answer to these questions is somehow "yes", the amygdala reacts instantly in the form of a neural alarm and transmits the message to the rest of the brain that there is a crisis. The amygdala has a rich communication network with the brain. In an emergency, it controls and directs a large part of the brain, including the rational mind. The structures in the limbic system are experts in learning and remembering processes, and the amygdala in emotional states.

Amygdala; It functions according to the principle of comparing the experienced moment with previous events. This event is the same or not. It has an extremely careless evaluation system. It allows for unwarranted impulsive reactions as it misses important details.

Is it possible to prevent the primitive-impulsive responses caused by the neural impulses that pass indirectly to the amygdala?

In this phase, the prefrontal cortex acts as a buffer. This region softens the primitive impulses in the amygdala and limbic region, allowing emotions to turn into more analytical or reasonable responses. In a sense, it suppresses the feelings and calms our worries.

The prefrontal cortex is responsible for working memory. it controls the healthy and conscious functioning of the memory. There are circuits between the prefrontal memory and the limbic system (lower brain), and the presence of these circuits provides control of the prefrontal cortex. Strong emotions such as fear, anger, and anxiety negatively affect control and prevent healthy thinking.

Feelings as the market crashes, money lost, and the warning amygdala. In fact, the amygdala does its job. It does its job in the prefrontal cortex. The system is perfectly designed. If you can use this designed system, no problem. If you have set the stop level. If you can persuade yourself to sell at the stop. (In this persuasion process, past experiences, simulations, etc. are effective.) The amygdala starts to ring when you fall into the stoma. In a perfect voice.

There are also waves emitted by the brain regarding the brain. These waves have a voltage as low as one-millionth of a volt. Each type of wave is associated with one stage of the state of consciousness. If a coordinated transition cannot be achieved between these waves, various problems arise. For example, if delta and theta waves do not occur when necessary, insomnia begins to occur in the person.

Using Brain Waves.
Operating devices using brain waves is no longer a dream. Scientists at Duke University transferred the brain waves to a computer with electrodes they placed in the brains of monkeys.

“The waves obtained when the monkeys made various movements were collected in a computer. The brain waves obtained during simple movements such as holding an object or clapping hands were analyzed by the computer and converted into signals, and these signals were transformed into three-dimensional images and transferred to a robot arm connected to a computer, thus enabling the movement of the arm. "

BRAIN WAVES

British physicist Richard Caton discovered in 1875 the existence of electric current in the brain that is emitted by the rhythm. German scientist Hans Berger (1873-1941) succeeded in recording the electrical activation of the brain on paper with an ordinary radio device - EEG (electroencephalograph) - which he made in 1924. For this reason, NEUROFEEDBACK TRAINING owes its present existence to HANS BERGER. According to Berger's research, brain waves changed according to the state of consciousness and oscillated at different frequencies. These brain waves at different frequencies were divided into 4 main groups and named Beta, Alpha, Theta, and Delta.

BETA: It changes between 13 and 30 Hz. Beta is the waking rhythm of the brain. In other words, they are waves that enable active thinking about the world we live in, being interested, being able to concentrate, and solving daily problems. High beta activity causes anxiety and aggression.

ALPHA: It varies between 7.5 (8) -12 Hz. Alpha waves are waves that provide awareness, quick grasp and attention. We need adequate generation of alpha waves when solving mathematical problems and carefully following lectures or meetings. When the Alpha waves watch normally, we can easily finish any work we take into our hands and experience the feeling of calmness and peace. We see and understand the world as it is.

THETA: Theta frequencies range from 4 to 8 Hz. A good theta activity is the source of learning and especially creativity. It is a wavelength that we are intuitive with, where there is no stress. The intensity of activity is high for children aged 2 to 5, so it is very important to support creativity in this age range but to teach reality appropriately.

DELTA: It takes place in frequencies of 0 - 4 Hz. Often in sleep and rarely in deep meditation, it can be said that some frequencies in the delta band emit growth hormone and therefore deep sleep is a very important wavelength for rest and rejuvenation. Delta band usually occurs in infants during stages 3 and 4 of adults' sleep. It is the wavelength at which brain activity is slowest.
