Fig. 6.
Transmission (A) and electron energy loss spectroscopic micrographs (B, C, ΔE = 150 ± 10 eV) of the synaptosomal fraction. A large nerve terminal with many mitochondria and synaptic vesicles is shown inA. The arrows point to dense spots that may be interpreted as ribosomes. In B andC, many single and clustered ribosome-like signals occur within large nerve terminals. The small arrows inB point to profiles of synaptic vesicles. Magnification, 40,000×. Scale bar, 0.5 μm.
