Recent studies have reported metabolic change during visual and motor stimulation using MRS at 7T MRI system. We think there is potential to perform fMRS experiments at 3T system. Visual stimuli were given with block design consisting of 2 black-white movie clips and 3 rest sections. Our preliminary results showed that Glu concentrations in visual cortex increases by 1.39% during watching movie, while NAA and Cre have no significant change. The observed Glu change was comparable to previous study performed at 7T.
