Effects of exogenous serotonin and dopamine on thermotaxis memory behavior in tph-1 or bas-1 mutants.

(A–B) Effects of exogenous serotonin on thermotaxis memory behavior in tph-1 mutants. (C–D) Effects of exogenous serotonin on thermotaxis memory behavior in bas-1 mutants. (E–F) Effects of exogenous dopamine on thermotaxis memory behavior in bas-1 mutants. Serotonin or dopamine was dissolved in M9 buffer and spread on the NGM plates at a final concentration of 2 mM or 5 mM. The normalized isothermal tracking behavior (IT) values were used. 5-HT, serotonin; DA, dopamine. Bars represent means ± S.E.M. *p<0.05, **p<0.01. NS, no significance.
