Electron micrograph of two labeled CT terminals (t1*, t2*) in the dorsal zone of the NTS of a sodium-restricted rat containing unlabeled inclusions (p), which are identified as finger-like protrusions from other neuropil. Lack of microtubules and vesicles suggest p1 and p2 may be emerging from postsynaptic spines. A third protrusion (p3) is identified as a segment from a terminal, based on the presence of vesicles within. One of the labeled terminals (t1*) formed synapses (arrows) with two separate dendrites (d1, d2). An unlabeled terminal (t1) also formed a synapse (arrow) with one of these dendrites (d1). Surrounding glia (g) suggests a glomerular structure. m; mitochondria. Scale bar = 0.5 μm.
