What Is an EEG
Do you know that your brain is also a hotspot for much chaotic electrical activity? In fact, the truth is that the brain really works because of such electronic impulses and also such electronic waves made in the skull. Even when you are sound asleep, your mind continues to feed electrical impulses from time to time. This means that you dream when the electrical activity becomes too distinct inside your brain. So, if you want to know all about the different patterns of electrical current in your brain, you would need to go in for an EEG procedure. An EEG procedure means Electroencephalography. It is the complex process of measuring the electrical impulses in the brain. Let’s know more about EEG procedures.
You would be wondering what does an EEG actually attempt to measure. The answer is quite simple. The main areas of study in an EEG process is the neurons and the other electrically active parts of the anatomy of the brain. The EEG is done for people when they are suffering from some sort of mental disturbances or defects. Problems like epilepsy and other such mental afflictions can be diagnosed only if the electrical activity is measured with detailed procedure. One such procedure is the EEG. It is applied especially in the lobes and neurons of the part of the brain. These are the places where most of the electrical impulses and other activity actually takes place in the case of epilepsy and other serious mental problems.
The process of EEG is also used a main method to understand or indicate the adversity caused by severe mental problems as well. If the person is suffering from mental problems like abnormal behavior or is at the risk of becoming unconscious or comatose, the readings of the EEG will be a good way to understand the real nature of the problems. To identify the different patterns and rates of the electrical activity in the brain, different frequency bands are used to indicate the differing patterns of the impulses. Some frequencies would be generally high and they would imply that the mind is active and the human being is alert and normally healthy. However, a considerably slower pattern of electrical activity in brain implies a definite unconsciousness.
However, this is normally also a setback to the entire diagnosis of serious mental problems like coma or even brain death. This is because it is generally not easy to select out the real problems from the other, more common forms of unconsciousness like sound sleep or mere dizziness. In any form of rest and mental relaxation, the electrical activity becomes considerably less and almost indistinct. When this happens, the doctors usually make the mistake of perceiving it as some serious problem with the brain. However, apart from this, the recordings of irregular or even agitated electronic activity in the organ could be indicators or measuring rods of some of the major behavioral disorders. So, this much can be diagnosed or confirmed with an EEG.
The process of EEG is a handy tool for reading and measuring the variation and fluctuating patterns of the electrical impulses in the brain. It is widely used to confirm the existence of mental and serious behavioral problems as well. However, it may not be used for diagnosing unconsciousness. Still, this process helps us to understand mental behavioral problems better without any great difficulty.
