Figure 4

Changes in the olfactory preference in the T-maze due to heat. A) The repellent responses to 10-1.5 vol/vol ethanol in water are reduced in wildtype flies due to the heat treatment [IO = number flies on odor side/(number flies on odor + control sides); IO > 0.5 indicates attraction, IO = 0.5 indicates indifference, and 0 < IO < 0.5 indicates repellency). B) Olfactory responses to 10-1.5 ethanol in flies with reduced levels of the Orco co-receptor compared with control flies of the same genetic background. C) The repellent responses to 10-0.5 ethanol are reduced in orco null mutants due to the heat treatment. D) Temperature protocol for the control C and experimental E flies shown in panels A) and C). Note that the behavioral response was measured for both groups at the same temperature and therefore at the same odorant concentration in the gas phase.
