AP PSYCHOLOGY

Detailed explanation-1: -To study the brain, scientists can use a machine called an MRI (magnetic resonance imaging) scanner. An MRI scanner takes pictures of the brain in a safe way, allowing scientists to learn about the structure of the brain and its functions.

Detailed explanation-2: -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-3: -Functional magnetic resonance imaging (fMRI) measures the small changes in blood flow that occur with brain activity. It may be used to examine which parts of the brain are handling critical functions, evaluate the effects of stroke or other disease, or to guide brain treatment.

Detailed explanation-4: -Most commonly, clinicians and researchers use functional magnetic resonance imaging (fMRI) to measure brain activity via fluctuations in blood oxygen levels. However, a lot of vital brain activity information is lost using fMRI because blood oxygen levels take about six seconds to respond to a stimulus.

Detailed explanation-5: -Electroencephalography (EEG) Whereas fMRI records blood flow, a proxy of neuron activation, EEG directly records the brain’s electrical activity via electrodes placed on the scalp of the subject.
