Using fMRI we tested brain activations involved in temporal processing following Fast ForWord (FFW) training in 11 young volunteers. They performed the Temporal Order Judgment task in two sessions: before and after the training. The task was to report the order of two sounds presented in rapid succession. Each pair consisted of a short (10-ms) and a long (50-ms) sound separated by Inter-Stimulus-Intervals of 160 ms (easy condition), 60 ms (medium) and 10 ms (diffi cult). FFW training was applied for ca. 8 weeks with four 1-hour sessions per week. The brain activations during particular conditions (“before vs. after” and “after vs. before”) the training were compared using paired sample t-tests from SPM5. ‘Before vs. after’ comparisons resulted in the following activations: (1) easy condition – left cerebellum, (2) medium condition – cerebellum and insula bilaterally, left thalamus and putamen and moreover, bilaterally selected areas of the temporal, frontal and parietal lobes, (3) diffi cult condition – left insula and the left temporal, frontal and parietal gyri. “After vs. before” comparisons showed no signifi cant differences for each condition, thus, indicating no increase of activation “after” than “before” the training. These results support the involvement of above structures in timing and suggest decreased brain activation in timing tasks following FFW training. We thank Scientifi c Learning for the opportunity to use FFW grant MSHE no.: 1082/P01/2006/31.
