Peptide profiling of the four major song nuclei by mass spectrometry. The homogenates of four major song nuclei (from top to bottom: LMAN, Area X, HVC, and RA) were analysed by MALDI-TOF MS. (A) Peptide profile of four song nuclei in the m/z range of 870-5000. (B) Magnified spectrum between 870-2200 m/z. The individual peaks were mass-matched to peptides previously shown to be present in the brain via tandem mass spectrometry.
