AP PSYCHOLOGY

Detailed explanation-1: -A form of MRI known as functional MRI (fMRI) has emerged as the most prominent neuroimaging technology over the last two decades. fMRI tracks changes in blood flow and oxygen levels to indicate neural activity.

Detailed explanation-2: -An event-related potential (ERP) is the measured brain response that is the direct result of a specific sensory, cognitive, or motor event. More formally, it is any stereotyped electrophysiological response to a stimulus. The study of the brain in this way provides a noninvasive means of evaluating brain functioning.

Detailed explanation-3: -A key advantage of ERP methods is that they provide measures of neural activity with very high temporal resolution. The superior temporal resolution of ERPs makes them well suited to examinations of neural events responsible for human memory, which can potentially be monitored on a millisecond-by-millisecond basis.

Detailed explanation-4: -The three most common and most frequently used measures are functional Magnetic Resonance Imaging (fMRI), magnetoencephalography (MEG) and electroencephalography (EEG).
