Fig 4
Neurodegenerative changes observed in the brains of stranded dolphins.
(A) MB silver staining illustrates AD-like compact neuritic plaque in the ACtx of a stranded dolphin. (B) A representative digital scan of an ill-defined agrophyllic plaque containing dystrophic neurites. (C) Dense neuropil threads were observed in the VCtx. (D, E) agrophyllic neurons containing dystrophic neurites. (F) Coiled body in the ACtx. Representative scale bars: 50 μm.
