Elektroensefalografia

Elektroensefalografia, commonly referred to as EEG, is a non-invasive medical procedure used to record the electrical activity of the brain. This technique involves placing electrodes on the scalp to detect and amplify the tiny electrical charges that result from ionic current flows within the neurons of the brain. EEG is widely used in clinical settings to diagnose and monitor various neurological conditions, including epilepsy, sleep disorders, and brain injuries.

The procedure is relatively simple and painless. The electrodes are typically made of conductive materials such as silver chloride and are attached to the scalp using a conductive gel or paste to ensure good electrical contact. The signals are then transmitted to an amplifier and displayed on a monitor in real-time, allowing healthcare professionals to observe the brain's electrical activity.

EEG is particularly useful for identifying abnormal patterns of brain activity, such as seizures or abnormal rhythms, which can help in the diagnosis and management of neurological disorders. It is also valuable in research settings, where it can be used to study brain function, cognition, and the effects of various treatments.

Despite its advantages, EEG has limitations. The resolution of EEG is relatively low compared to other imaging techniques, and it can be affected by factors such as muscle activity, eye movements, and the presence of artifacts. Additionally, EEG signals are often contaminated by noise, which can make interpretation challenging.

In summary, elektroensefalografia is a valuable tool in the diagnosis and monitoring of neurological conditions. Its non-invasive nature and relatively low cost make it accessible for widespread use in clinical and research settings. However, its limitations must be considered when interpreting the results.
