| |Description=3-D fMRI map of regions in the brain that exhibit blood flow changes in response to visual stimulation. Scientists are using powerful MRI machines which allow, noninvasively, for the localization and visualization of active brain regions. Functional MRI (fMRI), a technique that measures small and localized blood flow changes that follow increase in neuronal activity in the brain, was done on a ultra-high field magnet (9.4 Tesla) using high spatial resolution (0.15 x 0.15 mm). The image shows in great detail a 3-D fMRI map of regions in the visual cortex that exhibit larger blood flow changes in response to visual stimulation. The functional map is overlaid on a high resolution anatomical image.
