Functional Magnetic Resonance Imaging has become an important analytical tool to study neurodegenerative diseases. We used EPI-BOLD fMRI technique to acquire functional images of patients with familial essential tremor (FET) disorder and healthy control volunteers, during the same motor task activity. Functional images were used to produce brain activation maps of the patients and volunteers. These functional maps of the primary somatosensorial and motor cortexes of patients and control subjects were compared for functional differences. The averaged functional brain images of eight of each case are presented, it can be observed that there are differences in active zones. The results presented in this work show that there are differences in functional maps during motor task activation between control subjects and FET patients suggesting a cerebral functional reorganization or plasticity, that can be mapped with BOLD-fMRI.
