The description in the passage matches the procedure used to obtain an EEG reading, where metal disks (electrodes) are attached to the scalp to measure the electrical activity in the brain, which is then translated into wave patterns on a piece of paper. CT scans and functional magnetic resonance imaging (fMRI) are other methods used for brain imaging but involve different techniques that do not match the description in the passage. Microelectrodes are tiny, thin wires used to measure activity in specific neurons or brain regions and are not typically used for obtaining a broad overview of brain activity across different parts of the brain.
