This is an important issue, of great interest to professionals working in neurology and its different areas, such as neuropediatrics, neurophysiology and neuroradiology. For this reason, I have prepared this article with everything you need to know about the EEG, popularly called a head scan, but which has different uses in monitoring and diagnosing the health of the central nervous system. Whether an abnormal or normal electroencephalogram, it is imperative that the report be clear and of good quality . After all, the results of the examination are decisive in determining the need for treatment for some type of disease and even the required approach to the case. With that in mind, proceed to the next topics to understand.
What an electroencephalogram is
It is used for, how the test is perform. What are the possible results and what characterizes a normal electroencephalogram report. What is an electroencephalogram? normal EEG Patient being prepared to perform. EEG Electroencephalogram is a test that evaluates the spontaneous electrical activity of the brain. To this end, the test. Also known by its abbreviation EEG. Amplifies brain electrical impulses and records them in order to detect neurological abnormalities. It should also be cleric that neurons are cells that act in the reception. Conduction and transmission of electrical signals. emit to control the actions carried out by the human body. Thus, through electrodes fixed on the scalp. The electroencephalogram records the activity of these cells in the form of frequency. The frequency corresponds to the number of times the same signal is repeated each second.
In the brain frequency naturally varies
In this way, neurons that vibrate at the same frequency tend to come together and form groups. During the EEG, light stimuli are triggered at certain frequencies. Then, the neurons that vibrate at that frequency send a response. Which is collected by the electrodes and expressed DT Leads through a tracing. Although recent technological advances have greatly qualia the test, it is not new, as it was create in 1929 by the German psychiatrist and neurologist. Hans Berger . Since then, it has been consider of paramount importance by the medical community around the world. What is the use of the electroencephalogram? Children’s EEG cap Child performing an EEG The electroencephalogram serves to detect changes in brain activity. This exam is essential to investigate possible dysfunctions of consciousness, vascular alterations and disorders that affect the brain or central nervous system, such as epilepsy .
