Question

Describe the working of a Elecrtroencephalogram or WEDEEG.

Answer 1

Electroencephalogram or EEG is the recording done for the brain waves or potentials generated by the currents of the emitting brain. The instrument used for this is EEG or called as electroencephalogram. The specific mode for obtaining right collection of an electroencephalogram by means of an instrument is called electroencephalography, in this particular graphs are made for the recording of CSF and other types of waves. For thins the electrodes in particular are used of the instrument which are further applied to various skull points at various points. The frequency and the amplitudes are pre-decided for these waves, as, they differ in different states (excited, drowsy, asleep, relaxed, angry, deep sleep, sleep walking, etc.) and further implied by what neurological condition does the person have. EEG, therefore, has an important diagnostic value for multitude of individuals with many factors applied to it. Brain waves are classified into four main types- Alpha, Beta, Delta and Theta.
1)Alpha waves: They are typical of an awake resting person, or just woke up from a deep or short periods of sleep or nap. Alpha waves emanate from the occipital lobe region and have an approximated frequency of 8-13 per seconds.
2)Beta waves: These are the brain waves during some strenuous physical and mental activity has been performed, such as immense logical thinking Andy rigorous activity beyond a individual's limit. They are mainly emanated from the parietal lobe and frontal lobal regions having an approximated frequency of 18-30 per second.
3) Delta waves: They occur when subdued into a state of deep sleep, infants and serious brain disorder and dysfunctional mind thinking, such as, Alzheimer at the chronic last stage of surviving will produce these kinds of brain waves into a signal formation. Frequency is particularly really low in these cases approximated towards below the range, 3-5 per second.
4) Theta Waves: These types of brain waves are quite frequently seen particularly in children and also some grown up adults with a severe class of chronic stress which is hard to get off from, affecting the brain wave. The frequency of these brain waves are approximated towards 4-7 per second.
