= Neu-Imaging techniques are used to obtain images of brain functioning and structures = -> Helpful to understand the relationship between cognitive processes and behavior

-Measure important functions in the brain e.g. glucose consumption and blood flow

-It is used to detect brain tumors or memory disorders e.g. Alzheimer's disease

-It can identify cellular level metabolic changes in an organ or tissue

-By using this technology, Alzheimer's disease can be detected in the early stages.

**2) MRI (Magnetic Resonance Imaging)**






-MRI provides a three-dimensional picture of brain structures -MRI and fMRI (functional magnetic resonance imaging) work by detecting changes in the use of oxygen in the blood. =>When an area in the brain is more active, it uses more oxygen. -The scanners can be also used in marketing research in order to detect which areas are active.
