Extended Data Figure 4

Altruistic responses (orange) reinforced on FR2, FR4 and FR6 and selfish responses (blue) reinforced on FR1 expressed as percentage of the total in males (light blue, (n=7) and females (red, n=4) mice and responses on the preferred nose poke (NP1, dark grey) reinforced on FR2, FR4 and FR6 and responses on the non-preferred nose poke (NP2, light grey) reinforced on FR1 in mice tested without recipient (n=6) (FR2: two-way RM ANOVA, group (with recipient males, with recipient females, no recipient) x response (FR1, FR2), F(2, 13)=3.5, p=0.05. FR4: two-way RM ANOVA, group (with recipient males, with recipient females, no recipient) x response (FR1, FR2), F(2, 13)=5.1, p=0.0192; FR6. two-way RM ANOVA, group (with recipient males, with recipient females, no recipient) x response (FR1, FR2), F(2, 13)=6.6, p=0.0103. FR8: two-tailed unpaired t-test, t=8.32, d.f.=6, p=0.0002). *p<0.05, **p<0.01, ***p<0.005 n.s. not significant. Values are expressed as mean ± s.e.m.
