Cognitive neuroscience is a cross- disciplinary area that tries to find out how the brain 'produces' cognitive functions such as thinking, memory and attention. A breakthrough in this area is the use of modern techniques that can reproduce the human brain during work. One such technique is positron emission tomography (PET). This imaging technique measures brain activity by measuring blodflow, that is related to degree of neural activity.

Changes in bloodflow in specific regions, related to a cognitive activity, can be described by visualizing the data in a standardized brain atlas.

VRlab has together with the insitute for Psychology developed a tool, PETviewer, to visualize PET-data on a intuitive and understandable way.
