Time–activity curves of 1-11C-acetate uptake in the human visual cortex normalized to injected activity per kg bodyweight yielding standardized uptake values (SUV). The curves represent mean data from all six human experiments. During visual stimulation the clearance of 11C activity is larger compared with baseline. Note also the modestly faster wash-in of radioactivity during stimulation.
