## Abstract Saturation recovery spectra (STEAM) were acquired at 1.5 T with 7 __TR__s ranging from 530 to 5000 ms and a constant __TE__ of 30 ms in voxels (7.2 ml) located in occipital grey, parietal white and frontal white matter (10 subjects each location). Spectra were also acquired at 7, 21 and
