Energy metabolism of the human visual cortex was investigated, by performing 31P fMRS. The used setup was optimized for high SNR by using a dedicated 31P RF coil at 7T and a visual stimulus with a large visual angle. Changes in the up-field peak of inorganic phosphate (Pi) are observed, revealing new promising opportunities to measure energy metabolism in the human visual cortex.
