Summary

Stroke has been considered one of the main causes of long-term disability in the adult population, and is no longer considered a disease of the elderly, since 2/3 of all strokes occur among people under 70 years of age. According to the Ministry of Health, stroke is responsible for 40% of early retirements, being one of the most important causes of mortality in Brazil. The electroencephalogram (EEG) has been shown to be a very useful tool in the study of functional status and for the diagnosis of brain damage and disorders. It is considered a simple, non-invasive test with high temporal resolution, being a method widely used in laboratories to non-invasively monitor brain activity.

electroencephalogram

The EEG is the recording of electrical activity in the brain in different regions of the cortex. The capture of electrical signals is performed by attaching electrodes to the surface of the scalp. As the EEG signal has an amplitude in microvolts (µVpp) it is necessary to use amplifiers, leaving the signal possible to be registered. The electrode-electrolyte interface is very important and must be able to provide a good connection between the skin and the conductive material of the electrode, otherwise the EEG signal, in addition to being contaminated by noise, may suffer distortion.
