A partial neuronal network mediating chemotaxis and thermotaxis behavior. Triangles represent sensory neurons and hexagons represent interneurons. Sodium chloride is detected mainly by ASE, with minor contributions by ADF, ASG and ASI [4]. Thermosensory AFD neurons and AIY and AIZ interneurons play critical roles in thermotaxis behavior [12]. The number of synapses and gap junctions are based on White et al. [1]. The arrows represent chemical synapses and the H-shaped bar represents the gap junction. The relative quantity of synaptic connections is represented by line thickness (thin lines: three or fewer synapses; thick line: 16 or more synapses; intermediate line: 4 ~15 synapses).
