NMDA-induced ultrastructural changes in RGCs at 7 days where necrotic cell in the form of highly electron-dense neuronal debris (Red star, A & B, Bar = 2 μm) is seen lying adjacent to numerous membrane-bound microtubule-rich neuritic processes (C, red triangle, Bar = 2 μm) identified as dendrites under high power (D, red triangle, Bar = 500 nm); Figure E and F show reactive microglia surrounding the dendritic sprouts. (Bars = 2 μm).
