elektroenkefalografiaan

Elektroenkefalografia (EEG) is a non-invasive medical procedure used to record electrical activity in the brain. It involves placing electrodes on the scalp to detect and amplify the tiny electrical signals generated by the brain's neurons. These signals are then processed and displayed as waveforms on a monitor, providing a real-time view of brain activity.

EEG is commonly used in clinical settings to diagnose and monitor various neurological conditions, such as epilepsy, sleep disorders, and brain injuries. It is also utilized in research to study brain function and behavior. The procedure is generally safe and well-tolerated, with minimal risks associated with it. However, it may cause mild discomfort or irritation at the electrode sites, and in rare cases, it can lead to allergic reactions or skin irritations.

EEG has several advantages over other brain imaging techniques. It is relatively inexpensive, portable, and can be performed in real-time, making it suitable for continuous monitoring. Additionally, EEG does not expose patients to ionizing radiation, unlike techniques such as computed tomography (CT) or magnetic resonance imaging (MRI).

Despite its benefits, EEG has limitations. The spatial resolution of EEG is relatively low, as the signals detected are an average of the activity from a large number of neurons. Furthermore, EEG is sensitive to artifacts, such as muscle activity or movement, which can obscure the brain signals. Despite these limitations, EEG remains a valuable tool in the field of neuroscience and clinical practice.
