The description mentions metal disks on Miranda's scalp connected to a machine that translates electrical energy from her brain into wavy lines on paper. This is a classic description of an electroencephalogram (EEG), which measures brain activity through electrodes placed on the scalp. Option A (CT scan) uses X-rays to produce detailed images of the brain's structures, while option B (functional magnetic resonance imaging) uses strong magnetic fields to measure changes in blood flow in the brain. Option C (microelectrode) involves a tiny electrode inserted into the brain tissue to directly measure neuronal activity.
