Figure 1 Serotonin and PDF Signaling Generate Behavioral States in C. elegans (A) C. elegans worms cycle between roaming and dwelling states. Serotonin signaling promotes dwelling, whereas PDF signaling promotes roaming. (B) Schematic circuit diagram shows that some neurons (orange) are directly inhibited by serotonin, whereas other neurons (yellow) are directly activated by PDF. The two signals converge on some neurons (red) to exert opposing effects. Cell 2013 154, 955-956DOI: (10.1016/j.cell.2013.08.017) Copyright © 2013 Elsevier Inc. Terms and Conditions
