Fig. 3.

Graphical representation of connections between receptors and pathways implicated in NTS baroreflex modulation by pharmacological studies. These pathways are canonical and provide an abstract representation of events downstream from receptors. Although the general structure of each pathway is common to all receptors activating a given canonical pathway, the individual participants and isoforms may vary. Gray-shaded receptors are tachycardic and white receptors are bradycardic. See Table 4, columns 3–6 for references.
