What is electroencephalography?

Electroencephalography (EEG) is a non-invasive diagnostic technique that measures electrical activity in the brain using electrodes placed on the scalp. It captures brain wave patterns, which can help diagnose conditions such as epilepsy, sleep disorders, and brain injuries. EEG is commonly used in both clinical settings and research to study brain function and assess cognitive processes. The resulting recordings, known as electroencephalograms, provide valuable insights into neural activity and brain health.
