In each condition, the frequency of the brain are changing. Based on research over the years in many developed countries, the frequency of the human brain is different for each phase of conscious, relaxed, light sleep, deep sleep, trance, panic, and so forth. This can be measured with electrical equipment Ensefalo Acrylamide / EEG. Electrical Ensefalo Acrylamide (EEG) is a tool that studies the picture of recording electrical activity in the brain, including EEG recording techniques and interpretation. Neurons in the cortex of the brain out electrical waves with a very small voltage (mV), which is then channeled to an EEG machine to terekamlah elektroenselogram amplified so that its size enough to be captured by the reader's eyes as waves of EEG delta, alpha, beta, theta , gamma etc..
Getting the EEG recording is good and right is one of the main objectives of the EEG examination other than the correct interpretation. EEG is a tool to support the establishment of diagnosis, as long as we can get the recording is good and right. Records that are not good it will mislead the establishment of diagnosis.
The best time is while recording so that the drug-free brain waves (Brainwave) who obtained the Brain Waves (Brainwave) that is free from the influence of drugs. Old recording of at least 15-20 minutes in conscious patients. If there is a procedure fotik stimulation, hyperventilation and sleep so long the recording should be added. EEG is the sample time of a person's life, and time of 20 minutes is a very short time to draw a conclusion from an employer or a person's brain function. Therefore, the longer the recording, the more likely we are to find abnormalitasnya.
Hans Berger, inventor of electroencephalogram (EEG)
Hans Berger is a professor of psychiatry and director of the Psychiatric University Clinic of Jena (1919-1938). However, he is famous not because of it. He became leader of the world due to outstanding contributions in the study of human brain activity and consciousness. This research even led to the discovery of a device that changes the treasures of medical science. His name is the electroencephalogram (EEG).
Electroencephalogram is a tool that is able to visualize the brain waves (Brainwave) humans in the form of graphs. Brain Waves (Brainwave) was measured on the basis of any potential differences that occur repeatedly in between the electrodes are connected to a human head.
At first, Berger makes EEG only as a tool to measure brain waves (Brainwave). But it turns out, over time, the EEG be used as a tool that is able to diagnose and treat certain diseases, such as epilepsy and brain tumors. It is also very priceless.
Hans Berger was born on May 21, 1873. He is a German national, rather originated from a small town north of Bavaria Neuses near Coburg. Berger is the son of a physician, Paul Friedrich Berger. His mother, Anna Rückert is the son of a German poet. Berger is strongly influenced by both parents. That is why, Hans Berger many referred to as a philosophical scientist.
Hans Berger graduated with honors from the Gymnasium in Coburg. Then he enrolled at the University of Berlin as a student of Astronomy in 1892. The following year, he volunteered for the German army.
His decision to become a volunteer military have almost made a fatal accident. However, his sister told his father about this. Her father is worried immediately sent a telegram to ensure it. And luckily, Berger survived. Events that made his sister makes Berger confused. Why could his sister knew that Mr. Berger will have an accident? Though they are far apart and never communicate. Berger finally realized that between him and his brother have telepathic bond that can not be proved by reason.
In 1897, he received a medical degree and became a junior staff of the psychiatric clinic that would make it direktu. 1901, Berger became a lecturer. In that year also, he memublikasikanpenelitiannya on human brain function and note its size based on the modification of blood circulation.
In early 1902, he became famous. This is because he recorded his research on the activity of cerebral cortex (brain) dogs. However, in 1910, he was desperate for a result that is not so meaningful. Berger also got a dead end will research on the physics of energy that affects the brain
Having had time to volunteer at the hospital Rethel, France, he returned to Germany and was elected director of the university psychiatric clinic in Jena. In his first few years as a director, Berger conducted research on the relationship between brain and soul. However, in a state of leisure he was doing personal research on the electrical activity in the brain. During this time, Berger was known as being disciplined. The time taken in many studies.
From the results of his research he menyimpulka that in the human brain there are brain waves (Brainwave).
The equipment used is very rough Berger. He uses the ring Edelmann galvanometer as a tool pencatatnya. But because the cleverness and wit, Berger finally able to find a tool that can record brain waves (Brainwave) this. His name is the electroencephalogram (EEG) that the discovery on July 6, 1924. Names of patients who make it work this is a young man named Zedel.
Berger continued his research for 5 years before finally publishing this tool to the public. Patients not only people suffering from disorders of the head, but also a normal person. In doing research, he put the electrodes on the front of the head and the back of the head.
In 1929, Berger published his findings in a prestigious forum Archiv für Psychiatrie und Nervenkrankheiten, and the title "Über das Elektrenkephalogramm des Menschen" became the first article of the fourteenth, published writings on the EEG in the period 1929-1938. All three articles were able to prove the existence of brain waves (Brainwave).
Hans Berger was married in 1911 with technical assistant clinic, Baroness Ursula von Bulow. They have four children.
In his native country, Germany, Berger did not much concern. The reason the Nazis in power in Germany do not believe in Berger who had joined the Western Front. In 1938, Berger was forced to stop his research. Laboratories dismantled and he moved to the small town of Bad Blankenburg in Thuringia. He also experienced a prolonged depression. And on June 1, 1941, he ended his life by hanging himself.
