From: Heavy metals in locus ceruleus and motor neurons in motor neuron disease
Comparison of LC heavy metal staining in SALS, SPMA and FMND patients. (A) The percentage of LC neurons containing heavy metals varied widely in all MND subgroups, particularly in the SMND group, but was not significantly different between groups. Bars = median values. (B) All MND subgroups had more high (upper 50% of range) than low (lower 50% of range) category LC neurons containing heavy metals, with no significant differences between groups.
