Abstract :
fMRI is a non-invasive technique to evaluate brain areas related to a requested task. The event-related fMRI is one kind of its design, which permits not only spatial resolution, but also temporal correlation. This information may be more easily understood by the clinicians, if showed in a dynamic way. The aim of this paper is to describe a fMRI visualization system to expose the brain images, in the best view to stand out the areas of activity as long as they appear. It will empower the technique, not only to impress the clinicians, but also to enhance the importance of temporal connectivities. This system will be a module of the CAVERNA virtual reality
