Explain the use of technology in investigating cognitive processes.

= Brain Imaging Techniques:  =

PET Scan (Positron Emission Tomography)

 * ==Scanning method of measuring blood glucose in the brain==
 * ==Can be used to detect abnormalities due to disease (eg, Alzheimer's, Parkinson's), damage from physical trauma, and psychological disorders (eg, schizophrenia)==
 * ==Image: a PET scan showing abnormalities caused by Alzheimer's==



MRI Scan (Magnetic Resonance Imaging)

 * ==Three-dimensional picture of the brain==
 * ==Detects oxygen in the blood to see which part of the brain is active (areas using more oxygen are more active)==
 * ==Functional MRIs work by showing which are is active while problem solving, reading, etc==

Brain imaging techniques and CLOA:

 * == Investigation of brain damage (such as the cases of HM and Clive Wearing) ==
 * ==Diseases relating to cognitive processes (eg memory) can be studied. For examples, Mosconi used PET to detect early-onset Alzheimer's- page 86)==
