Webb10 feb. 2024 · fMRI is a hemodynamic method that measures the amount of deoxygenated blood in parts of the brain (Ward, 2016). The amount of deoxygenated blood gives off a BOLD signal (Blood-Oxygen-Level Dependent) and convert into voxels (form of pixels) which allow us to see a 3D image of the brain and to track the neural activity (Martin & … Webb10 nov. 2024 · Disadvantages of fMRI. fMRI studies of brain cancer, lesions and other brain pathologies of humans and animals are still to be explored.
