English: L-canavanine triggers the premature proboscis retraction after the PER. This movie illustrates the behavior of WT fly when their leg tarsi are in contact with either a 100 mM sucrose solution (sucrose) or a 100 mM sucrose + 40 mM l-canavanine (sucrose/canavanine) solution. Soon after the sucrose stimulation, PER occurs, and flies usually sustain their proboscis extension to search for food. When the legs are in contact with the sucrose/canavanine solution, PER occurs normally, but the fly retracts its proboscis just after, leading to the end of food searching. Thus, l-canavanine triggers avoidance behavior by premature PR. |
