Extended Data Fig. 8: Cases of axon-sharing between spines.
From: Learning binds new inputs into functional synaptic clusters via spinogenesis
Two additional example cases of axon sharing between spines on imaged dendrites. The left-most column shows reconstructions of the dendrites and its spines along with the axon being shared between two spines. Each synapse occurring with the dendrite of interest is circled, and corresponding EM images illustrating synaptic contact are shown on the right (further indicated with red arrows). The top example shows a double connection between two pre-existing spines immediately after a dendritic branch point. The bottom example shows a double connection formed by a new spine and a nearby pre-existing spine.
