English: Caffeine and L-canavanine trigger the premature proboscis retraction after the PER. This movie illustrates the behavior of WT flies when their leg tarsi are in contact with either a 100 mM sucrose + 40 mM l-canavanine (sucrose/canavanine) solution or a 100 mM sucrose + 50 mM caffeine (sucrose/caffeine) solution. Generally, caffeine inhibits the sucrose-induced PER. However, this effect is not complete as some flies extend their proboscis as shown in this video. Similar to the l-canavanine–induced effect, the majority of those flies retract their proboscis just after PER in the presence of caffeine. |
