Figure 1.
polySia immunoreactivity in the dorsal vagal complex. A, polySia immunoreactivity (ir) is abundant in the NTS, area postrema (AP), and dorsal motor nucleus of the vagus (10N) but not the solitary tract (ST) or surrounding regions (bregma level −14.00 mm). B, polySia-ir is seen throughout the NTS and dorsal motor nucleus of the vagus. Bi, Bii, polySia-ir puncta present throughout the neuropil and enveloping some unlabeled neurons. Ci, Cii, polySia-ir (white) closely apposes but rarely colocalizes with synaptophysin-ir (green) within the NTS.
