Figure 2.

Lick‐cluster analysis (LCA) showing hedonic response to increasing sucrose concentration in wild‐type (WT) and Prader–Willi syndrome (PWS)^ICdel mice. (A) Lick‐cluster size (LCS) increases with increasing sucrose concentration, showing a linear relationship between this hedonic measure and palatability. However, there was no statistical different between WT and PWS ^ICdel mice in LCS measures across all sucrose concentrations. Similarly, (B) inter‐lick interval (ILI) and (C) total number of licks were also equivalent in WT and PWS ^ICdel mice. Data shown are mean ± SEM.
