Figure 8

GC-MS m/z chromatograms of stable isotope dilution assay of human cerebral cortex. H3-BMAA (m/z 116 and 245, arrows) along with its deuterated standard (m/z 119 and 248, arrows) were detected in the extractable fraction, also called free BMAA, in samples spiked ex vivo with 250 pg/μl H3-BMAA (A). No H3-BMAA was detected in any human sample that was not spiked (B).
