Food intake in PWScr^m+/p−, PWScr^m+/p− and PWScr^m−/p− mutants. (A) Representation of the working-for-food behavior in automated home cages. (B) Food intake of PWScr^m+/p+ (n = 6), PWScr^m+/p− (n = 6), and PWScr^m−/p− (n = 5) was defined as cumulative food intake across days of the experiment. The means ± SEM are shown. Significant differences are indicated as follows: $\ast P<\mathrm{0.05.}$
