Electroencephalography (EEG) is a non-invasive neurophysiological test that measures and records the electrical activity of the brain. It is commonly used to assess brain function and diagnose various neurological conditions. The EEG recording represents the collective electrical activity generated by the firing of neurons (brain cells) in the cerebral cortex.
Small metal electrodes are attached to the scalp using a conductive gel or paste. These electrodes are strategically placed at specific locations to capture electrical signals from different regions of the brain.The electrical activity of the brain is recorded in the form of brain waves. These brain waves are categorized into different frequency bands, each associated with different states of consciousness, attention, and relaxation.
