Suitable techniques include MRI, fMRI and PET imaging but what is important is that you understand how they are used by psychologists to study the relationship between brain and behaviour (remember the IB accept cognitive processes, such as memory, as a behaviour).
http://www.pbs.org/wnet/brain/scanning/index.html This site gives a basic description of the different brain imaging techniques.
PET scans: pet-scans with information from Smith and Jonides (1997)

In an ERQ you may wish to talk about (and/or compare) more than one technique, so I have provided some materials in MRI and fMRI too.

Useful to evaluate studies which use brain imaging; if they don’t control motivation, conclusions may not be valid: also another example of a study using fMRI scans.

Examples of studies that have used virtual reality
A very interesting study as it looks at the cross over between emotion(affect), cognition and biology and uses virtual reality so ideal for IB! Performance on a Virtual Reality Spatial Memory Navigation Task in Depressed Patients — Gould et al_ 164 (3) 516 — Am J Psychiatry.mht

The choice of techniques used to correlate the brain with behaviour is based on a variety of factors including ….
- available technology
An awareness of these limitations as well as the strengths of these different techniques is important when evaluating the contribution they have made to understanding behaviour.
