Any irregularities may be a sign of seizures or other brain disorders. These lines allow neurologists to quickly assess whether there are abnormal patterns.

The electrical impulses in an EEG recording look like wavy lines with peaks and valleys. The electrodes analyze the electrical impulses in the brain and send signals to a computer, where the results are recorded. Small, metal discs called electrodes are attached to the scalp with a specialized conductive cream. The EEG test tracks and records brain wave patterns. Brain cells communicate with each other through electrical impulses, and an EEG can be used to help detect potential problems associated with this activity. » View all COVID-19 information What is an EEG?Īn electroencephalogram (EEG) is a test used to evaluate the electrical activity in the brain.
