An important aspect in brain activation studies is the relationship between neuronal activity and measurable indices of function. We applied functional magnetic resonance imaging (fMRI) to investigate blood flow-related MR signal changes in response to different rates of repetitive movements of the index finger. The contralateral precentral gyrus and the posterior frontomesial cortex revealed a significant increase in MR signal over baseline for 1, 2 and 3 Hz finger movements, with a linear… CONTINUE READING
