elektroenkantoiminnan

Elektroenkantoiminnan is a Finnish term that translates to "electroencephalography" in English. It is a non-invasive neurophysiological monitoring method used to record the electrical activity of the brain. This activity is detected by electrodes placed on the scalp, which pick up the tiny electrical charges that result from brain cell activity. The recorded signals are then amplified and displayed as wavy lines on a monitor or paper, representing different brain wave frequencies.

Electroencephalography is primarily used for diagnosing and monitoring various neurological conditions. It is a crucial tool for identifying seizure disorders, such as epilepsy, by detecting abnormal patterns of electrical discharge. It can also help in the diagnosis of sleep disorders, brain tumors, stroke, and other brain injuries or diseases that affect brain function. Furthermore, EEG can be used to assess brain activity in patients in a coma or those undergoing anesthesia, and to monitor the effectiveness of treatments for certain neurological conditions.

The procedure itself is painless and generally safe. A technician will attach small metal discs (electrodes) to specific points on the patient's scalp using a conductive paste or gel. The patient is typically asked to sit or lie down quietly during the recording, which can last from 20 minutes to several hours, depending on the clinical need. Sometimes, the patient may be asked to perform certain actions, such as opening and closing their eyes, or taking deep breaths, to elicit specific brain responses. Despite its widespread use, the interpretation of EEG results requires specialized training and expertise, as the signals can be influenced by various factors, including movement and muscle activity.
