Synchrotron infrared spectromicroscopy and X-Ray Fluorescence spectromicroscopy have been applied to imagine human central nervous system tissue. Untreated, flash frozen tissue samples were analyzed at micron level spatial resolution to obtain information about chemical composition of the sample. Bright synchrotron light allowed the high spatial resolution (8-10 microns) needed for this study. In the family of neurodegenerative diseases, Amyotrophic Lateral Sclerosis (ALS) is the most frequent cause of adult onset. ALS symptoms include: generalized weakness and muscle atrophy. The...
