| Popis: | 105 Functional magnetic resonance spectroscopy of brain has been used to study brain metabolism during activation. Recent studies have reported metabolic change during visual and motor stimuli using MRS at 7 Tesla MRI system. In these studies, glutamate (Glu) and lactate (Lac) have been found to increase by 2% and 17% during stimuli using block design in fMRS experiments. We think there is potential to perform fMRS experiments at 3 Tesla system. Chaplin’s comedy movies were selected as stimuli material and voxel is located at visual cortex. Visual stimuli were given with block design consisting of 1 baseline section, 2 black-white movie clips sections and 2 rest sections. Our preliminary results showed that concentration of metabolites do not have significant change. But in further analysis show that it still has chance to find the concentration change using fMRS in 3 Tesla system if experiment is adjusted. |
