Aim: Functional magnetic resonance imaging (fMRI) was used to map active areas of the brain during visual working memory processing in a group of 8 healthy volunteers and two patients - one patient with a cavernoma in the right auditory cortex and one patient with dysplasia in the right frontal lobes.

Method: The process of memorizing projected playing cards was used to stimulate visual working memory (VWM) areas. In order to compare visual WM activation with speech related areas, we used the verbal fluency test.

Results: Functional maps showed bilateral activation in the frontal lobes and in the parietal-occipital lobes.

Conclusion: In comparison with verbal fluency (VF) test significant activations was found in the right frontal lobe.

Keywords: fMRI, cavernoma, verbal fluency, visual working memory
