PET scans can be used to show localisation of function within the brain. This three-dimensional PET scan shows the metabolic activity within the brain during a hand exercise. The exercise involved moving the fingers of the right hand. The front of the brain is at the left. The most active area appears white; this is the motor cortex in the cerebral cortex where movement is coordinated.

One of the most serious problems with cognitive neuropsychology stems from the difficulty in carrying out group studies. This has led to the increasing use of single-case studies. Such studies are sometimes very revealing. However, they can provide misleading evidence if the patient had specific cognitive deficits prior to brain damage, or if he or she has developed unusual compensatory strategies to cope with the consequences of brain damage.
