Ultra-high field MRI (at 7T or more) gives exceptionally clear measurement of the structure and responses of the human brain. This excellent signal-to-noise ratio (SNR) is often used to image brain structure and function at very high resolution. However, at more conventional resolutions (between 1.5 and 2 mm), 7T fMRI allows us to characterize neural responses in much greater detail than 3T fMRI for several reasons. First, the spread of the 7T BOLD signal is far smaller than at 3T, giving a far more spatially specific signal even at the same nominal resolution.
