Final answer:
Jonas is likely having an electroencephalograph (EEG) done to measure the electrical activity in his brain.
Explanation:
Jonas is likely having an electroencephalograph (EEG) done by his doctor to measure the electrical activity in his brain. The EEG records brainwave patterns by placing electrodes on the surface of the skull, providing real-time information but not detailed brain structure images.
While computed tomography (CT) scans, magnetic resonance imaging (MRI), and positron emission tomography (PET) scans are also neuroimaging procedures commonly used to study brain activity, an EEG specifically focuses on measuring electrical brain activity.
