What mechanisms underlie the differential vulnerability of PMC vs FEF regions in ALS neurodegeneration?

OPEN

The study shows that PMC has significant NAA/Cr decrease and mIns/Cr increase, while FEF shows NAA/Cr decrease but no significant Cho/Cr changes. The molecular basis for this regional selectivity within closely related motor areas remains unexplained.
