Electroencephalography (eeg)

Explanation:

Electroencephalography or EEG as it is also called is an extremely important test able to analyze spontaneous brain electrical activity, where through the activity presented, it is possible to identify diseases and disorders of the central nervous system and possible changes that may be risk to the patient. Electroencephalographic data are captured through electrodes positioned on the scalp, which are able to measure the electrical activity of neuronal cells by detecting variations that may indicate specific pathologies.

Because it is a noninvasive and painless examination, it can be performed by several individuals at different ages and pathological conditions, with no contraindications as long as there are no impediments in the positioning of the electrodes on the scalp. This technique is often used in studies that investigate sleep patterns.
