Typical synaptosomes. Note: Typical synaptosomes examined by electron microscopy (EM). Synaptosomes were prepared with a Percoll gradient procedure. EM showed the presence of intact synaptic vesicles and the preservation of presynaptic and postsynaptic elements and a higher mitochondrial content and contained a few extrasynaptic mitochondria. Scale bar is 0.5 μm in (a and b) and 1 μm in (c and d)
