Psycology 101 and the basics of brain configuration

Noninvasive Brain Imaging Techniques
To document brain structure:
CT scans (Computerized Tomography)
Also called CAT scans (computerized axial tomography)
MRI scans (Magnetic Resonance Imaging)
fMRI scans (Functional Magnetic Resonance Imaging)
See below after discussion of the PET scan.

CT scans (Computerized tomography)
Synonymous with “CAT” scan (Computer-Axial Tomography)
Tomography = picture
several X-rays are taken of a thin slice of the brain from different vantage points while person is inside a large cylinder.
A Two-dimensional, often black and white photograph of a horizontal brain “slice” is produced by the computer
“For a full brain scan 180 separate scans are made.” (Reber & Reber, 2001, p. 139).
Least expensive of the brain imaging techniques.

MRI scans (Magnetic Resonance Ima...
