7.Methods: BOLD functional MRI scan covering the wh ole brain was performed on 11 healthy human subject during Event- relate designe d stimulation with sweet taste and tasteless control . The fMRI data was analyzed by SPM99(Statistical Parametric Mapping) software with statistic t-test to gene rate the activation map.
8.The data show that average annual NPP from 1982 to 1998 was 119.6 billion metric tons of organic matter, of which humans appropriated 20 percent. (The uncertainties are large, resulting in a range of 14 to 26 percent.) The map indicates human appropriation of NPP as a percentage of that produced locally.
