Which diagnostic test is utilized to measure electrical activity in the brain?

Explanation:
The electroencephalogram (EEG) is the diagnostic test specifically designed to measure the electrical activity of the brain. It involves placing electrodes on the scalp to capture and record the electrical impulses generated by brain cells as they communicate with each other. This technique is particularly valuable in diagnosing various neurological conditions, such as epilepsy, sleep disorders, and other abnormalities concerning brain function. In contrast, magnetic resonance imaging (MRI) and computed tomography (CT) scans are imaging techniques that visualize the structure of the brain and identify physical abnormalities such as tumors or bleeding, but they do not measure electrical activity. Positron emission tomography (PET) scans provide information about metabolic activity in the brain, often using radioactive tracers to assess brain function, but again, this is distinct from measuring electrical activity directly. Thus, the EEG stands out as the definitive test for assessing the brain’s electrical function.
