Lysosomes in Dendrites (IMAGE) University of California - San Diego Caption Lysosomes were identified in dendrites and dendritic spines using various techniques. Cultured neurons show lysosomes throughout neurons and in dendritic spines indicated in yellow (left and upper right); brain slices show a lysosome in the head of the spine highlighted in green (middle right); and transmission electron microscopy reveals a lysosome (black circle) near the base of a spine (bottom right).
