Zinc-enriched boutons in rat spinal cord.
The rat spinal cord reveals a complex pattern of zinc-enriched (ZEN) boutons. As a result of in vivo exposure to selenide ions, nanosized clusters of zinc selenide are created in places where zinc ions are present, including the zinc-containing synaptic vesicles of ZEN boutons. The clusters can be silver enhanced by autometallographic (AMG) development. A description of the ZEN bouton patterns is presented and discussed. The distribution of ZEN boutons could indicate that these terminal systems have a differentiated influence on sensory and motor systems.
