## Abstract In vivo ^1^H NMR spectroscopy at 7 T was utilized to measure the changes in lactate concentration upon repeated identical visual stimuli, each lasting for 2 min. The average amplitude of these increases was found to be reduced over time (__P__ < 0.01), from 0.13 ± 0.02 μmol/g during the
