Retrograde labeling of rostral ventrolateral medulla-projecting pPVN vasopressin neurons. Representative photomicrographs of coronal sections through the brain at the level of the PVN showing: a, b retrogradely labeled cells (fluorescent green), c, d vasopressin-positive cells (fluorescent red;) and (inset a + b; inset c + d) the co-localization of retrograde label and vasopressin protein. The bar graphs (mean ± SEM) present the number of e retrogradely labeled cells, f vasopressin-positive cells, g the number of retrogradely labeled + vasopressin-positive cells, as well as h percentage of retrogradely labeled cells expressing vasopressin, per section in the left parvocellular division of the PVN. There was no difference in the number of fluorescently stained cells (red and green) in MI rats (n = 8) compared to sham rats (n = 8; unpaired t-test). Scale bars = 50 μm. pPVN parvocellular paraventricular nucleus
