Detailed explanation-1: -Ways of Studying the Brain: Scanning Techniques, including Functional Magnetic Resonance Imaging (fMRI); Electroencephalogram (EEGs) and Event-Related Potentials (ERPs); Post-Mortem Examinations-Psychology Hub.
Detailed explanation-2: -Event-Related Potentials (ERPs) Event-Related Potentials (ERP) use similar equipment to EEG, i.e. electrodes attached to the scalp. However, the key difference is that a stimulus is presented to a participant (for example a picture/sound) and the researcher looks for activity related to that stimulus.
Detailed explanation-3: -Computed tomography (CT) scans are oblique X-ray slices that show the density of brain structures. Magnetic resonance imaging (MRI) uses changes in electrically charged molecules in a magnetic field to form images of the brain.
Detailed explanation-4: -ERP components are defined by their polarity (positive or negative going voltage), timing, scalp distribution, and sensitivity to task manipulations.
