An EEG measures electrical activity in the Blank______.Multiple choice question.brainheartmuscles

The correct answer is "brain."

Electroencephalography (EEG) is a non-invasive medical test that detects and records the electrical activity of the brain. This is accomplished by placing electrodes on the scalp, which capture the electrical signals generated by neuronal activity. The measured electrical impulses are then amplified and recorded as brain waves, which can be analyzed to assess various neurological conditions such as seizures, sleep disorders, and other brain pathologies. By monitoring these brain wave patterns, healthcare professionals can gain insights into the functioning of different brain regions and identify abnormalities in brain activity. Therefore, in this multiple-choice question, the EEG measures electrical activity in the brain.
