Figure 5.

Panel A data represent the mean ± standard error of the mean (SEM) of licks/30 s. Different letters represent statistically significant differences within the water-restriction treatments and * represent statistically significant differences between the water-restriction treatments based on Bonferroni-corrected planned comparisons (P < 0.05). Panel B data represent mean ± SEM average of licks/30 s for water and sucrose while both solutions are maintained at 20 °C. Filled triangles represent licking recorded when rats were water-restricted. The open triangles represent licking recorded when rats were unrestricted.
