## Abstract Changes in cerebral blood oxygenation and flow during prolonged activation of human visual cortex (6โ€min video projection) were monitored using highโ€resolution T~2~\*โ€ and T~1~โ€weighted gradientโ€echo MRI in identical sessions. Oxygenationโ€sensitive recordings displayed an initial signal

## 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 ยฑ 0.02 ฮผmol/g during the
