Figure 3: Ultrastructure of ipsilateral tectopulvinar terminals.

Figure 3:

(a-i) Terminals in the pulvinar nucleus (Pl and Pcm) labeled by a virus injection in the ipsilateral SC were identified by a dark reaction product in a subset of their synaptic vesicles. Labeled terminals are indicated by magenta overlay, black arrows indicate synapses, and postsynaptic dendrites and dendritic inclusions are indicated by yellow overlay. The labeled tectopulvinar terminals varied in size. The largest labeled terminals contained dendritic protrusions (a-d). e) The asterisk indicates a corticothalamic terminal labeled by a V1 virus injection. Scale bar in a = 400 nm and also applies to f. Scale bar in b = 600nm and also applies to c,d, and g-i.
