Elemental mapping of human nervous tissue using the scanning proton microprobe.
The scanning proton microprobe (SPM) is a powerful multi-elemental analytical instrument capable of elemental mapping at the parts per million level of sensitivity. In this report we demonstrate that the SPM is sufficiently sensitive and versatile to distinguish different regions of the human central nervous system on the basis of differences in their normal endogenous elemental composition.
