EEG

Electroencephalography (EEG) is a non-invasive test that records electrical activity generated by neurons in the brain. Small sensors called electrodes are placed on the scalp to detect these electrical signals, which are then amplified and displayed as wave patterns. EEG helps doctors study brain functions, diagnose neurological conditions like epilepsy, sleep disorders, and assess brain activity during coma or unconscious states. It provides real-time insights into brain dynamics, reflecting different mental states such as alertness, relaxation, or drowsiness. Overall, EEG is a valuable, safe tool for understanding and monitoring brain activity.
