Figure 6From: Immunohistochemical characterization of nodose cough receptor neurons projecting to the trachea of guinea pigsHistograms showing the size distribution of all nodose neurons (irrespective of fluorogold tracing) that express (A) substance P (SP), calcitonin gene-related peptide (CGRP) or somatostatin (SST), and (B) neuronal nitric oxide synthase (nNOS). In panel B nNOS all denotes all nNOS immunoreactive cells whereas nNOS IFCs denotes only nNOS intensely fluorescent cells. The superimposed solid lines show the moving averages associated with each histogram and the dashed line references the size distribution of fluorogold (FG) traced neurons shown in figure 2.Back to article page
