Licking measures for a 2 and 20% sucrose solution, following 4 h food deprivation, in PENK (a–c) or BEND (d–f) KOs and their respective wild-type mice. (a, d) Total licks during 30 min sessions for PENK KO (n=13), BEND KO (n=8), and their respective wild types (n=17 and n=8, respectively). (b, e) Total number of licking bouts during the session. (c, f) Mean length of licking bouts. Data were averaged across 4 test days for each animal and are presented as mean±SEM. Horizontal and vertical bars with asterisks (*) indicate statistically significant (p<0.05) main effects of sucrose concentration and genotype, respectively. Pound sign (#) indicates significant (p<0.05) day x genotype interaction.
