Figure 4.
Examples of synapses formed by PHAL-labeled PVT axons terminals in BL. (a-d) Four examples of PHAL-labeled axon terminals (PHAL-t) forming asymmetric synapses with dendritic spines (s). (e) Example of PVT axon terminal forming an asymmetric synapse with a dendritic profile (d). (f) The sole example of PVT axon terminal forming a symmetric synapse with a dendritic profile (d). Scale bar in d applies to panels a-d. Scale bar in f applies to panels e and f.
