Figure 17.
Graphical representation of lickometer data. (A) Fluid intake presented as the average number of licks. (B) Lick response to tastant normalized to lick response to water (lick ratio). A lick ratio of 1 indicates that equal amounts of water and tastant were consumed. A lick ratio <1 indicates that water was preferred over tastant, and a lick ratio >1 indicates that tastant was preferred over water.
