How to get an fmri
Current clinical application is mainly used for the positioning of the functional cortical center, including vision, movement, and hearing. BOLD-fMRI has become a valuable tool for presurgical functional brain mapping. In surgery, BOLD-fMRI can guide the safest surgical trajectory between functionally viable brain tissue and the lesion.In fMRI the blood-oxygen-level dependent (BOLD) signal is recorded by the MRI machine which is an indirect measure of activity within the brain. In order to perform our analysis we first need to ...
