Procedures to independently control fly hunger and thirst states.
(a) Protocol to produce exclusively hungry or thirsty flies for 6 h water memory retrieval. (b) Consumption assays confirm that flies
housed on dry sugar for 6 h after training are thirsty but not hungry; on 1% agar for 6 h, hungry but not thirsty; and are fully satiated if
kept on food. Flies kept on dry sugar for 6 h after training consume a significant amount of water in 2 min, whereas flies on 1% agar or
fly food for 6 h do not drink (P>0.1 compared to zero, n=4; one sample t-test). Conversely, flies on 1% agar for 6 h after training eat a
similar amount of 3M sucrose as flies starved on 1% agar for 21 h (P=0.07, n=4; ANOVA followed by post hoc Tukey HSD test), while
the other two groups eat significantly less (P<0.0001, n=4; ANOVA followed by post hoc Tukey HSD test) and are not different from one
another (P=0.33, n=4; ANOVA followed by post hoc Tukey HSD test). (c) Protocol to produce flies that are exclusively hungry or thirsty
for 24 h sugar memory retrieval. (d) Consumption assays confirm that flies kept on 1% agar for 21 h are hungry but not thirsty; on
drierite and dry sugar for 6 h, thirsty but not hungry; and are fully satiated if kept on food for 24 h. Flies on 1% agar for 21 h or fly food
for 24 h do not drink (P>0.1 compared to zero, n=4; one sample t-test), whereas flies on drierite and dry sugar for 6 h consume an
amount of water in 2 min that is indistinguishable from 16 h water deprived flies (P=0.14, n=4; ANOVA followed by post hoc Tukey HSD
test). In contrast, flies kept on 1% agar for 21 h eat a significant amount of 3M sucrose while the other two groups eat significantly less
(P<0.0001, n=4; ANOVA followed by post hoc Tukey HSD test) and are not different from one another (P=0.14, n=4; ANOVA followed
by post hoc Tukey HSD test).

is no significant difference between the transgenic DopR1 mutant fly strains (P=0.42, n=8; ANOVA followed by post hoc Tukey HSD

Water learning, wanting and liking can be mechanistically distinguished by manipulating subpopulations of R48B04
rewarding dopaminergic neurons.
Dopaminergic neurons innervating γ4 provide reinforcement for water learning and others to β′2 that are labeled by both R48B04 and
0104 are required for naïve water-seeking. Learned wanting and liking are apparently independent of the naïve wanting and learning
neurons. Nature Neuroscience: doi:10.1038/nn.3827
