Supplementary Figure 1. Conceptual model of the low threshold pathway. Chemotaxis results from two complementary behaviors: avoidance responses triggered by decreases in concentration and approach responses triggered by increases in concentration. The ASE neurons are the main chemosensory neurons of the downstep pathway. The sensory neurons for the upstep pathway have not been identified. However, the neurons ADF, ASI, and ASG are likely candidates based on previous laser ablation studies (Bargmann and Horvitz, 1991).

Supplementary Movie 1. Real-time movie of a crawling worm on the concentration clamp apparatus. The behavioral state and the NaCl concentration are displayed at the bottom of the movie. The baseline concentration of NaCl (C0) was 50 mM with a concentration step (?C) of -50 mM, resulting in a final concentration of 0 mM. The three main behavioral states are exhibited, as well as a specific reaction (increased turning) to the downstep.
