Answer;
Brain waves
During EEG measurements, 6-10 electrodes are attached to the scalp and produce line drawings that represent brain waves.
Explanation;
-An electroencephalogram (EEG) is a noninvasive test that records electrical patterns in the brain. It is a recording of the electrical activity of the brain from the scalp. The recorded wave forms reflect the cortical electrical activity.The test is used to help diagnose conditions such as seizures, epilepsy, head injuries, dizziness, headaches, brain tumors and sleeping problems. It can also be used to confirm brain death.
-Brainwaves are produced by synchronized electrical pulses from masses of neurons communicating with each other. Brainwaves are detected using sensors placed on the scalp.
