PARAFAC signal intensity from mouse cerebrum from control diet group in (A) Column one retention time window, and (B) Column two retention time window. (C) Total ion current showing lack of BMAA peak. (D) Mass spectral data from PARAFAC for this sample indicating that BMAA was not detected in this sample. Non-bold lines in panels (A) and (B) indicate loadings that are due to noise, baseline, or other analytes. See ref [32].
