Our aim was to know the relationship between oxygen inhalation and mitochondrial activity, and relationship between vision and mitochondrial activity as well. Eleven healthy volunteers underwent 31P MRS examination. ATP, ATP, ATP, and potential of hydrogen (pH) were measured. We can observe increased ATP, ATP, and ATP peaks on the 3rd scan breathing hyperoxic air with eyes opening. Brain mitochondrial activities were increased and more ATPs were produced after oxygen inhalation in healthy volunteers. More energy is needed in visual status.
